Answer: In Exercises 710, use the same population of {4, 5, 9} that was used in Examples

Chapter 6, Problem 8

(choose chapter or problem)

In Exercises 710, 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.Sampling Distribution of the Sample Standard Deviation For the following, round results to three decimal places.a. Find the value of the population standard deviation .b. Table 63 describes the sampling distribution of the sample mean. Construct a similar table representing the sampling distribution of the samplestandard deviation s. Then combine values of s that are the same, as in Table 64. (Hint: See Example 1 for Tables 63 and 64 that describe thesampling distribution of the sample mean.)c. Find the mean of the sampling distribution of the sample standard deviation.d. Based on the preceding results, is the sample standard deviation an unbiased estimator of the population standard deviation? Why or why not?
