Question

I need help with parts a AND b (towards the bottom of the page), please and thank you 

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 = 900 72 = 400 number making claims = 153 number making claims O (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 p2₂ = claim rate for married male policy holders.) O Ho: P₁-P₂ ≤ 0 H₂: P₁-P₂ > 0 Ho: P₁ P₂ #0 Ha: P₁-P₂ = 0 O Ho: P₁-P₂ >0 H₂: P₁-P₂ ≤ 0 Ho: P₁ P₂ = 0 Ha: P1-P₂ #0 Ho: P₁ P₂ 20 Ha: P₁ P₂ <0 = Find the p-value. (Round your answer to four decimal places.) p-value = 32 Find the value of the test statistic. (Round your answer to two decimal places.) X State your conclusion. Do not reject Ho. We can not conclude that there is a difference between claim rates. Reject Ho. We can not conclude that there is a difference between claim rates. 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. to (b) Provide a 95% confidence interval for the difference between the proportions for the two populations. (Round your answers to four decimal places.)
