To study the variability of in a test with grades from 0 to 5, 17 students were drawn from a school and their grades were as follows: 0, 1, 2, 1, 3, 1, 2, 1, 2, 1, 1, 2, 3, 4, 5, 3, 1. To estimate the variance, the estimators in the figure below were proposed. Get the estimates and discuss which is the "best" estimator.

Actuaries use various parameters when evaluating the cost of a life insurance policy. The variance of the life spans of a population is one of the parameters used for the evaluation. Each year, the actuaries at a particular insurance company randomly sample 30 people who died during the year (with the samples chosen independently from year to year) to see whether the variance of life spans has changed. The life span data from this year and from last year are summarized below. Current Last Year Year *1 = 75.8 x2 = 76.2 s3 = 47.61 s3= 92.16 (The first row gives the sample means and the second row gives the sample variances.) Assume that life spans are approximately normally distributed for each of the populations of people who died this year and people who died last year. Can we conclude, at the 0.05 significance level, that the variance of the life span for the current year, of, differs from the variance of the life span for last year, o,? Perform a two-tailed test.
