The null hypothesis for a binomial test states that p = 1/5.What is the z-score for X = 29 in a sample of n = 100?
A)z = 4/5
B)z = 9/5
C)z = 9/4
D)z = 9/16

The z-score for a binomial test is calculated as (X - np) / sqrt(np(1-p)). In this case, X = 29, n = 100, and p = 1/5. Plugging these values into the formula, we get (29 - 100(1/5)) / sqrt(100(1/5)(4/5)) = 9/4.
