Answer:
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
