I had a quiz. I want to know if I got this right..

The amount of students who enrolled in AP statistics and dropped out is 13%.

A company wants to test a computer program to see if it is effective to help the students.

They then took a sample of students who used the product. Out of 203 students, 11% of the students dropped out.

Whats the meaning of P-value?

Of course what is pvalue?

What would you say about this? Is the product effective?

What I did was find p-value and then did a confidence interval.

Can someone do it so I can see if I was right? thanks!
