1, sample Automobile collision insurance is used to pay for any claims made against the driver in the event of an accident. This type of insurance will typically pay to repair any assets that your vehicle damages. Arandom sample of40 collision claims of 20- to 24year-old drivers results in a mean claim of $4590 with a standard deviation of 32315. An independent random sample of 40 collision claims of 30- to 59-year-old drivers results in a mean claim M53669 with a standard deviation of $2029. Using the concept of hypothesis testing, determine if a higher insurance premium should be paid by 20- to 24-year-old drivers. Use a u = 0.01 level of signicance, and let population 1 be 20- to 24~year old drivers and population 2 be 30- to 59-year old drivers. Complete parts (a) through (e) below. (a) Collision claims tend to be skewed right. Why do you think this is the case? *A. There are a few very large collision claims relative to the majority of claims. 'x B. There are no very large collision claims. C. There are many large collision claims relative to the majority of claims. (b) What type of test should be used? A. A hypothesis test regarding the difference between two population proportions from independent samples * B. A hypothesis test regarding the dilierence of two means using Welch's approximate t J'C. Ahypothesis test regarding two population standard deviations D.

Most claims are high, but there are some claims that are much lower than the average. D. Most claims are moderate, but there are some claims that are much higher than the average. (b) A random sample of 40 collision claims of 30- to 59-year-old drivers results in a mean claim of $3680 with a standard deviation of $2030. An independent random sample of 40 collision claims of 20- to 24-year-old drivers results in a mean claim of $4536 with a standard deviation of $2306. Using the concept of hypothesis testing, determine if a higher insurance premium should be paid by 20- to 24-year-old drivers. Use a a = 0.10 level of significance. Let population 1 be all collision claims of 30- to 59-year-old drivers and let population 2 be all collision claims of 20- to 24-year-old drivers. Write the hypotheses for the test.

Reject the null hypothesis and conclude there is sufficient evidence that the mean claim of 30- to 59-year-old drivers is less than the mean claim of 20- to 24-year-old drivers at the o = 0.10 level of significance. It seems that 20- to 24-year-old drivers should pay a higher insurance premium.
