(Let P1 = claim rate for single male policyholders and P2 = claim rate for married male policy holders.) Ho: P1 - P2 = 0 HP2 - P20 Ho: P1 - P2 > 0 HP1-P2 SO o Ho: P1 - P20 H: P1 - P2 = 0 Ho: P1 - P220 H: P1-P2 < 0 Ho: P1 - P250 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 H.
