Question:

of the Sample Variance
a. Find the value of the population variance s2.
b. Table describes the sampling of the sample mean. Construct a similar table representing the sampling of the sample variance s2. Then combine values of s2 that are the same, as in Table.
c. Find the mean of the sampling of the sample variance.
d. Based on the preceding results, is the sample variance an unbiased estimator of the population variance? Why or why not?
Use the same population of {4, 5, 9} that was used in Examples 1 and 5. As in Examples 1 and 5, assume that samples of size n = 2 are randomly selected with replacement.
