e the appropriate technology to answer this question. 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 n, = 900 number making claims = 68 number making claims = 72 (a) Use a = 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.) Ho: P1 - P2 0 O Ha: P1 - P2 = 0 Ho: P1 - P2 50 O Ha: P1 - P2 > 0 Ho: P1 - - P2 20 OH: P1 - P2 7 0 O Ha: P1 - P2 s Ho: P1 - P2 = 0 OH: 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 Ho. We can not conclude that there is a difference between claim rates. O Reject Ho. We can not conclude that there is a difference between claim rates. O Reject Ho. We can conclude that there is a difference between claim rates. O Do not reject Ho. We can conclude that there is a difference between claim rates. (b ) Provide a 95% confidence interval for the difference between the proportions for the two populations. (Round you answers to four decimal places.) to
