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:

Number of “Yes”

Decisions per Candidate Frequency 0 22 1 36 2 23 3 8 4 1 Total 90

a. Using a = 0.05, perform a chi-square 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.
