3. Insurance company A claims that its customers pay less for car insurance, on average, than customers of its competitor, Company B. You wonder if this is true, so you decide to compare the average monthly costs of similar insurance policy from the two companies. For a random sample of 9 people who buy insurance from company A, the mean cost is $152 per month with a sample standard deviation of $17. For 11 randomly selected customers of company B, you find that they pay a mean of $155 per month with a sample standard deviation of $14. Assume that the population variances are not equal, and test Company A’s claim at the 0.01 level of significant. State the Hyp: Test Value is_____=______ P-value = ________ Decision:__________________________________________________
