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

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!

Rebecca Hu
01:05:33
Multiply by 3

Alex xi
01:08:37

YeJin Ahn
01:11:40
Thank you professor!!!
Michael navruzyan
01:12:04
