Suppose that candidates for a job opening at Citibank interview with four different managers. Each manager independently evaluates each candidate with a “yes” or “no” hiring decision. The following table shows the number of “yes” decisions given the last 90 candidates:

a. Using α = 0.05, perform a chisquare test to determine if the number of “yes” decisions per candidate follows the binomial probability distribution when the probability of a candidate receiving a “yes” vote is 30%.

b. Determine the p_value using Excel and interpret its meaning.
