A large automobile insurance company selected samples of single and married male policyholders and recorded the number who made an insurance claim over the preceding three-year period.

Single Policyholders Married Policyholders

n1 = 400

n2 = 900

number making claims = 76 number making claims = 90

(a)Use = 0.05. Test to determine whether the claim rates differ between single and married male policyholders.State the null and alternative hypotheses. (Let p1 = claim rate for single male policyholders and p2 = claim rate for married male policy holders.)

H0: p1 p2 0

Ha: p1 p2 > 0

H0: p1 p2 > 0

Ha: p1 p2 0

H0: p1 p2 0

Ha: p1 p2 < 0

H0: p1 p2 = 0

Ha: p1 p2 0

H0: p1 p2 0

Ha: p1 p2 = 0

Find the value of the test statistic.? (Round your answer to two decimal places.)Find the p-value.? (Round your answer to four decimal places.)p-value = State your conclusion.Do not reject H0. We can conclude that there is a difference between claim rates.Reject H0. We can conclude that there is a difference between claim rates. Reject H0.
