Assume a population of 1, 3, and 8. Assume that samples of size n = 2 are randomly selected with replacement from the population. Listed below are the nine different samples. Complete d below. 1,1 1,3 1,8 3,1 3,3 3,8 8,1 8,3 8,8 a. Find the value of the population standard deviation . = (Round to three decimal places as needed.) b. Find the standard deviation of each of the nine samples, then summarize the sampling distribution of the standard deviations in the format of a table representing the probability distribution of the distinct standard deviation values. Use ascending order of the sample standard deviations. S Probability (Type integers or fractions.) c. Find the mean of the sampling distribution of the sample standard deviations. The mean of the sampling distribution of the sample standard deviations is (Round to three decimal places as needed.) d. Do the sample standard deviations target the value of the population standard deviation? In general, do sample standard deviations make good estimators of population standard deviations? 'why not? OA. The sample standard deviations do not target the population standard deviation, therefore, sample standard deviations are biased estimators. OB. The sample standard deviations do target the population standard deviation, therefore, sample standard deviations are unbiased estimators. The sample standard deviations do target the population standard deviation, therefore, sample standard deviations are biased estimators. deviation therefore, sample standard deviations are unbiased estimators.
