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

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

Step-by-step 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
