6. Insurance companies track life expectancy information to assist in determining the cost of life insurance policies. They want to know if their clients this year have a longer life expectancy, on average, so the company randomly sampled 20 policyholders to see if the mean life expectancy of policyholders has increased. The mean life expectancy for the random sample was 78.6 years with a sample standard deviation of 5.12 years. The insurance company will only change their premium structure if...

USING R- STUDIO: Along with interest rates, life expectancy is a component in pricing financial annuities. Suppose that you know that last year life expectancy was 77 years for your annuity holders. Now you want to know if your clients this year have a longer life expectancy, on average, so you randomly sample n=20 of recently deceased annuity holders to see actual age at death. Using a 5% level of significance, test whether or not the new data shows evidence...
