Allstate Insurance is one of the major automobile insurance companies in the country. Recently, the western region claims manager instructed an intern in her department to test if there exists any difference between the mean years that male customers have been insured by Allstate versus female customers. The intern randomly selected 13 male and 13 female customers from the account records and the summary is given below (rounded to the nearest year).
Sample Mean - Male = 12, Sample Variance - Male = 3 Sample Mean - Female = 7, Sample Variance - Female = 4
a. Does this data suggest that there exists a difference in the average years insured by All State between male and female? Use α = 0.05.
b. Find the p-value for the test.
Please provide Hypothesis, Test Statistic, and Rejection Region Graph.

Problem 8.6 An automobile manufacturer recommends that any purchaser of one of its new cars bring it in to a dealer for a 3000-mile checkup. The company wishes to know whether the true average mileage for initial servicing differs from 3000. A random sample of 50 recent purchasers resulted in a sample average mileage of 3208 and a of 273 miles. Does the data strongly suggest that...
One male and one female dam rat pup were randomly selected from 8 litters to perform the swim maze. Each pup was placed in the water at one end of the maze and allowed to swim until it escaped at the opposite end. If the pup failed to escape after a certain period of time, it was placed at the beginning of the maze and given another chance. The experiment was repeated until each pup accomplished three successful escapes. The...

Insurance companies track life expectancy information to assist in determining the cost of life insurance policies. Life expectancy is a statistical measure of average time a person is expected to live, based on a number of demographic factors. Mathematically, life expectancy is the mean number of years of life remaining at a given age, assuming age-specific mortality rates remain at their most recently measured levels. Last year the average life expectancy of all the Life Insurance policyholders in Ontario...

7) Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test ie, describe the values of the test statistic that would result in rejection of the null hypothesis Suppose you wish to test the claim that the mean value of the differences d for a population of paired data, is greater than 0. Given a sample of n-15 and a significance level of a-001, what criterion would be used for rejecting the null hypothesis...

Suppose the national average dollar amount for an automobile insurance claim is $788.5. You work for an agency in Michigan and you are interested in whether or not the state average is greater than the national average. The hypotheses for this scenario are as follows: Null Hypothesis: μ ≤ 788.5, Alternative Hypothesis: μ > 788.5. You take a random sample of claims and calculate a p-value of 0.0851 based on the data, what is the appropriate conclusion? Conclude at the...
