isaacecheto

19:46

yep

YeJin Ahn

19:51

yup

Dorkhan Chang

20:13

0.401?

Justin Im

24:01

20/8=2.5 ?

Ryan Dai

24:03

20/8 should be 2.5?

YeJin Ahn

24:37

what would be the conclusion of the test?

Dorkhan Chang

25:25

so this would be a hypothesis test where the alternative is both tails?

Ryan Dai

25:31

i got 0.0455

Sophie

26:22

^same

ashley minooka

31:39

not effective

Sophie

31:54

treatment doesn't work

Matthew Simon

31:54

Proportions are the same

lauraherron

31:56

treatment ineffective

Alex xi

32:06

same distribution

YeJin Ahn

32:10

the treatment is effective

lauraherron

32:12

treatment doesn’t necessarily cause a difference

Dorkhan Chang

38:45

what's the 3rd word in "x=# of ..." in part c?

Sophie

39:17

pain ^

Dorkhan Chang

43:28

it's answered thanks though

Zehra Ali

44:42

why didn’t we do normal approximation?

isaacecheto

44:50

So the only difference is that we don’t use normal approximation?

isaacecheto

47:23

Ok thanks

isaacecheto

52:41

yep

ashley minooka

52:42

yes

Alex xi

52:42

yes

YeJin Ahn

52:44

yes

Forrest Kim

56:16

Thanks uncle Adam!

Alex xi

01:00:41

don’t you need to use n when you’re calculating the sd?

lauraherron

01:00:42

why the sort of 100 and not 400?

Dorkhan Chang

01:00:43

shouldn't it be 0.44/sqrt400

Alex xi

01:01:28

ok thank you

Rebecca Hu

01:01:49

How come sigma is not hypergeometric

Rebecca Hu

01:02:19

Because isn’t simple random sample without replacement?

Rebecca Hu

01:02:53

Ok thank you!

Rebecca Hu

01:02:53

Yes

YeJin Ahn

01:03:13

so sigma is formula for bernoulli?

YeJin Ahn

01:04:59

Got it, thank you!

YeJin Ahn

01:05:31

3 sds

Rebecca Hu

01:05:33

Multiply by 3

ashley minooka

01:05:34

3 sds

Michael navruzyan

01:08:03

why 0.95

Alex xi

01:08:37

Thank you professor!

Michael navruzyan

01:08:44

yes

Michael navruzyan

01:08:46

thanks

YeJin Ahn

01:09:05

why is this answer different from the answer from the previous question?

Claire MccCallick

01:09:37

Is there a chance you could upload the lecture notes for today before this weekend? I’d really appreciate it!

Michael navruzyan

01:11:12

how do you come up with the X as the Test Statistic in the Fisher exact questions

YeJin Ahn

01:11:40

Thank you professor!!!

Michael navruzyan

01:12:04

how do you know its # of pain related treatment patients

Michael navruzyan

01:12:12

relieved

Michael navruzyan

01:15:18

have a good weekend!
