Hypothesis testing

[Thomas74]

Hello everyone,

I have a question; there is a control group consisting of 9500 people, picked 475 people, and there is a pilot consisting of 500 people, picked 23 people. How do you do Hypothesis testing?

Here's how I do that; please correct me if I did wrong; I calculated with excel.

Alpha

0,1​

P-bar	475/9500=0,05​
P	23/500=0,046​
Z	(0,05-0,046)/sqrt(0,046*(1-0,0460)/(9500+500))=1,909443834​
P-Value	1-Normdist(1,909;0;1;TRUE)=0,02810243​

Thank you.
Thomas.

You didn't state the problem statement i.e. what are your null and alternate hypotheses?
