00:11:10	Nikki Marucut:	yes
00:11:11	Ekua-Yaaba Monkah:	my sis is pregooo
00:11:13	Nikki Marucut:	My brain hurts
00:11:14	Nikki Marucut:	LOL
00:11:15	Hiruni Jayasekera (she/her):	:(((( yikes
00:11:21	Hiruni Jayasekera (she/her):	congrats ekua!
00:11:25	Nikki Marucut:	Congrats  to your sister!!
00:11:25	Ekua-Yaaba Monkah:	found out two weeks ago!
00:11:32	Nikki Marucut:	Do you live near her?
00:11:33	Yulan Xie:	Congrats to your sister!!
00:11:39	Chitra Nambiar:	congrats Ekua!
00:11:54	Yulan Xie:	Not bad
00:12:01	Hiruni Jayasekera (she/her):	not bad but time crunch
00:12:04	Nikki Marucut:	I wish we had 10 more minutes
00:12:07	Olufunke Fasawe:	Time was short
00:12:09	Yulan Xie:	^^
00:12:09	Rachel Harvill:	^ same
00:12:13	Nikki Marucut:	I didn’t get to finish 2 or 3 problems
00:12:18	Stacy (Seohyun) Ahn:	It was v diff than practice test 🥲
00:12:26	Nikki Marucut:	And if I had 10 minutes it would have helped
00:12:27	Kelsey MacCuish:	https://docs.google.com/forms/d/e/1FAIpQLSf1eOrm0YGuOhi71E-kBR9EBeTO1_z9cKhWsdcN1FWQ9oAqjQ/viewform
00:13:23	Nikki Marucut:	It’s just hard when you take an exam at 7:40 am and it’s an exam
00:13:36	Christopher Patterson:	Is it too late to join a group for the project? I missed the deadline for the group survey. Also, is the project still reasonable to do alone ?
00:13:46	Nikki Marucut:	I felt I needed more time to acclimate to what I was doing if that makes sense?
00:14:17	Nikki Marucut:	Yes I definitely understand the time issue
00:14:39	Aliza Adler:	Kelsey, I’m just curious, has the midterm always been 75 minutes long? Or before COVID times and Zoom school was it 50 minutes?
00:14:48	Christopher Patterson:	OKay, thanks!
00:16:32	Ijeoma Uche:	Lab
00:16:33	Alexis O'Connor:	id rather do the lab
00:16:33	Jessica Fields (she/her/hers):	I’d be interested in maybe starting with the lab and then if time at the end we could go back to the quiz?
00:16:33	Ala Koreitem:	Can we go onto the lab?
00:16:34	Yulan Xie:	Lab plz~
00:16:34	Mariah Jiles (she/her):	I’d prefer to go through the lab
00:16:34	Phoenix Ding:	I want to directly go to lab
00:16:34	Aliza Adler:	I’d vote for lab please!
00:16:36	Genesis Navarrete:	lab
00:16:36	Lemlem Gebre:	Lab
00:16:38	Chitra Nambiar:	lab
00:16:38	Hiruni Jayasekera (she/her):	lab!
00:16:38	Leslie Giglio:	Could we work through lab, then quiz if time
00:16:42	Taylor Zehren:	My vote is to do the lab and if there’s time go into quiz questions after that
00:16:45	Nikki Marucut:	Echo lab
00:16:45	Olufunke Fasawe:	Lab
00:20:06	Mariah Jiles (she/her):	it will always occur
00:20:09	Christopher Patterson:	This even will always occur !
00:20:09	Lupita Ambriz:	always
00:20:10	Yulan Xie:	Always occurs
00:20:13	Phoenix Ding:	This event will almost always occur
00:21:02	Mariah Jiles (she/her):	it is unlikely
00:21:07	Ijeoma Uche:	This event is unlikely.
00:21:09	Leslie Giglio:	Unlikely
00:21:10	Phoenix Ding:	unlikely
00:21:13	Nikki Marucut:	Very rarely occur
00:21:13	Christopher Patterson:	very unlikely
00:21:14	Yulan Xie:	This event will very rarely occur
00:21:14	Aliza Adler:	It will very rarely occur
00:21:38	Nikki Marucut:	I would say .3 is unlikely
00:21:48	Nikki Marucut:	It gives the chance for some likelihood
00:21:55	Silvana Larrea:	This event will occur more often than not
00:21:57	Phoenix Ding:	Occur more often than not
00:22:00	Yulan Xie:	Happens often than not
00:22:21	Yulan Xie:	Almost always occurs
00:22:59	Nikki Marucut:	This is a very pretty graph
00:24:00	Nikki Marucut:	Yes!
00:24:02	Christopher Patterson:	clear!
00:24:03	Nikki Marucut:	Very clear
00:24:03	Yulan Xie:	yes
00:24:29	Olufunke Fasawe:	Are we still on Q1?
00:24:56	Annalisa Watson (she/her):	Q2! Describing the graph
00:25:13	Nikki Marucut:	You have to run the code to load the graph
00:25:15	Nikki Marucut:	FYI
00:26:11	Ijeoma Uche:	Almost certain?
00:26:47	Nikki Marucut:	They’re wider for responses like “we doubt”; and
00:26:49	Hiruni Jayasekera (she/her):	they others have larger ranges
00:26:52	Nikki Marucut:	There’s actually 3 humps
00:26:54	Olufunke Fasawe:	Thanks Nikki
00:27:39	Nikki Marucut:	You’re welcome Olufunke :)
00:30:11	Taylor Yoo:	heads or tails
00:32:28	Hiruni Jayasekera (she/her):	two heads or two tails?
00:32:40	Phoenix Ding:	Combined outcome of two coins
00:33:33	Annalisa Watson (she/her):	1 head and 1 tails
00:34:00	Annalisa Watson (she/her):	You flipped 1 coin twice
00:34:30	Julia Hankin:	Can you review size one more time?
00:34:32	Julia Hankin:	Sorry!
00:35:03	Hiruni Jayasekera (she/her):	flipping 1 coin 100 times
00:35:14	Annalisa Watson (she/her):	Size = # of coins
00:36:13	Julia Hankin:	Ah got it, thank you!!

00:42:46	Maddy Griffith:	60 1s, 40 0s
00:43:15	Silvana Larrea:	1 is the outcome we want to look at?
00:43:18	Hiruni Jayasekera (she/her):	it’s the probability of the event occurring which is 1
00:43:44	Maddy Griffith:	3 1s, 97 0s
00:43:46	Silvana Larrea:	3 1´s
00:44:37	Olufunke Fasawe:	Flu

00:44:44	Ekua-Yaaba Monkah:	heart disease
00:44:45	Nikki Marucut:	Scarlet fever
00:45:12	Nikki Marucut:	Scarlet fever have 20,000 cases a year in the US I believe
00:45:17	Olufunke Fasawe:	~50%
00:45:23	Stacy (Seohyun) Ahn:	probabity of people who actually get flu shots
00:45:39	Stacy (Seohyun) Ahn:	is around 50% in America!
00:45:47	Nikki Marucut:	yes
00:46:07	Chitra Nambiar:	allergic reaction to Tylenol
00:46:10	Phoenix Ding:	Some genetic disease
00:49:48	Mariah Jiles (she/her):	what is meant by sample space?
00:53:41	Phoenix Ding:	{0+, 0-, A+, A-, B+, B-, AB+, AB-}
00:53:42	Rachel Harvill:	S = {O+, O-, A+, A-, B+, B-, AB+, AB-}
00:53:48	Silvana Larrea:	S(0+, 0-, A+, A-, B+, B-, AB+, AB-)
00:54:21	Julia Hankin:	Does the order of the possible outcomes matter?
00:56:42	Ekua-Yaaba Monkah:	aren't the values we input provided above?
00:56:51	Hiruni Jayasekera (she/her):	I divided the percentage by 100
00:56:51	Silvana Larrea:	Since the probability is a number between 0 and 1 I divided the percentages given above for each blood type / 100
00:57:58	Ijeoma Uche:	P(Blood type = A+)= .27
00:58:00	Phoenix Ding:	0.27
00:58:14	Annalisa Watson (she/her):	Is the notation a percentage or decimal
00:58:24	Silvana Larrea:	Kelsey is it okay to right that notation as P(A+)?
00:58:26	Phoenix Ding:	0.73
00:58:27	Rachel Harvill:	1-0.27
00:58:42	Ijeoma Uche:	What’s the notation for not equal to
00:59:23	Silvana Larrea:	Ijeoma I think its P(A´) or P(Ac)
01:00:33	Ijeoma Uche:	1-.27
01:01:45	Annalisa Watson (she/her):	You could add up all the other blood types not including A+
01:01:47	Silvana Larrea:	Sum up all probabilities except the P(A+=
01:02:34	Ekua-Yaaba Monkah:	can u please explain the second way again?
01:02:52	Nikki Marucut:	^ yes
01:03:59	Ekua-Yaaba Monkah:	makes sense!
01:04:01	Nikki Marucut:	YES
01:05:06	Ijeoma Uche:	.40?
01:06:57	Lupita Ambriz:	P(.39+.01)= .40
01:09:32	Nikki Marucut:	Can you Go over the dependent bit agaibn
01:09:35	Nikki Marucut:	again*
01:10:08	Nikki Marucut:	…???
01:11:23	Nikki Marucut:	ahhhhhh
01:11:25	Nikki Marucut:	okay
01:11:26	Nikki Marucut:	Thank you!
01:12:40	Olufunke Fasawe:	If two events are independent, the probably of either event occurring is the sum of the individual probabilities for each one
01:13:34	Olufunke Fasawe:	OK
01:14:25	Olufunke Fasawe:	S= {Rh+, Rh-}
01:15:35	Ekua-Yaaba Monkah:	^^
01:15:38	Ala Koreitem:	^
01:16:05	Ijeoma Uche:	.50/.50
01:16:09	Rachel Harvill:	same

01:16:33	Phoenix Ding:	0.98/0.02
01:16:46	Annalisa Watson (she/her):	I thought it was adding the probabilities of negatives and positives from the previous blood types
01:16:49	Rachel Harvill:	Oh it’s for Asian American missed that
01:17:14	Ijeoma Uche:	^
01:17:37	Nikki Marucut:	I did too!
01:19:26	Nikki Marucut:	Yes!
01:21:28	Phoenix Ding:	yes
01:21:33	Lupita Ambriz:	yes
01:21:35	Taylor Yoo:	yes :)
01:25:00	Rachel Harvill:	What’s a practical use of the runif function?
01:26:03	Nikki Marucut:	So if we look at the graph you just made what does the 1 on the x axis equate to when using the runif code?
01:29:04	Rachel Harvill:	That’s helpful thank you
01:31:36	Nikki Marucut:	YES
01:31:41	Nikki Marucut:	Thank you for taking the time to explain that
01:34:14	Olufunke Fasawe:	Is it the area
01:34:17	Rachel Harvill:	Area of the square 1 * 0.4
01:34:17	Olufunke Fasawe:	0.4*1
01:36:14	Olufunke Fasawe:	How do you write the P as a code please?
01:36:29	Olufunke Fasawe:	We use the <- sign?
01:38:31	Mariah Jiles (she/her):	runif(n=1, min = 0, max= .4)
01:39:53	Mariah Jiles (she/her):	that makes sense 🙌🏾
01:40:15	Nikki Marucut:	P15 <- .4
01:40:28	Phoenix Ding:	area
01:40:31	Ekua-Yaaba Monkah:	all values underneath .4?
01:40:56	Phoenix Ding:	No??
01:41:53	Julia Hankin:	I’m a bit confused why it’s not different from the problem before, tbh! Since we don’t want to include 0.4 in the area
01:41:55	Silvana Larrea:	Maybe because in a continuous variable it would include like 0.3999999 or something?
01:44:27	Taylor Zehren:	0
01:45:24	Phoenix Ding:	0.4
01:45:25	Ekua-Yaaba Monkah:	0.4
01:45:30	Ekua-Yaaba Monkah:	0
01:45:31	Phoenix Ding:	0
01:45:58	Ekua-Yaaba Monkah:	still sinking in
01:46:12	Nikki Marucut:	Kind of! I think I need to let it marinate and come back to it
01:46:43	Phoenix Ding:	0
01:47:19	Phoenix Ding:	0.2
01:47:21	Phoenix Ding:	0.5-0.3
01:47:22	Taylor Zehren:	0.2
01:47:59	Olufunke Fasawe:	What is the answer to P15?
01:48:08	Nikki Marucut:	.4
01:48:26	Nikki Marucut:	0.4
01:50:06	Olufunke Fasawe:	Thank you
01:50:12	Nikki Marucut:	You’re welcome!
01:51:28	Nikki Marucut:	It’s good!
01:51:29	Ala Koreitem:	Yes!
01:51:30	Nikki Marucut:	yes
01:51:37	Nikki Marucut:	p17 <- 0.3 + 0.5
01:52:14	Nikki Marucut:	I did it because it includes everything below .3 and everything above .5
01:52:19	Nikki Marucut:	And I just ended up adding them
01:53:32	Nikki Marucut:	Yes!
01:53:48	Nikki Marucut:	You’re doing great! I’m ready to keep moving
01:55:20	Ijeoma Uche:	Just to check what did yay get for p19?
01:55:28	Ijeoma Uche:	you*
01:57:12	Lillian Man (she/her):	can you go over why p19 is 0?
01:57:44	Phoenix Ding:	punif(0.4, min = 0, max = 1)
01:59:20	Phoenix Ding:	punif(0.5, min = 0, max = 1)-punif(0.3, min = 0, max = 1)
02:01:06	Nikki Marucut:	p23 <- punif(0.5, min = 0, max = 1)+punif(0.3, min = 0, max = 1)
02:01:33	Annalisa Watson (she/her):	p23 <- punif(0.3, min = 0, max = 1) + punif(0.5, min = 0, max = 1, lower.tail = F)
02:01:35	Joyce Qiao:	punif(0.3, min = 0, max = 1) + punif(0.5, min = 0, max = 1, lower.tail = F)
02:01:58	Nikki Marucut:	min
02:02:02	Nikki Marucut:	ahhh
02:02:03	Nikki Marucut:	okay
02:05:56	Hiruni Jayasekera (she/her):	yes
