Question

Consider a binomial experiment with n trials and r successes. To construct a test for a proportion p, what value do we use for the z value of the sample test statistic?

r/n
(r/n)2
n/r
2r/n

Answer 1

value we use for z value of sample test is r/n

Explanation:

Given data

proportion p

trials = n

successes = r

to find out

what value we use for z value of sample test

solution

here

we know that

Probability of a success in single trail test = Number of successes/Number of trails

Probability of a success in single trail = r / n

so that

value we use for z value of sample test is r / n
