01:17:42 The ages of the 5 officers for a school club are 18, 18, 17, 16, and 15. The range of the distribution of ages is 3. The table displays all possible samples of size 2 and the corresponding ranges for each sample. Sample n = 2 Sample Range 18, 18 0 18, 17 1 18, 15 18, 17 1 18, 16 2 17, 16 18, 16 2 17, 15 ^ 18, 15 3 3 16, 1 1 2 Using the values in the table, is the sample range an unbiased estimator? Yes, 3 is the maximum of the sample ranges. Yes, the range of the sampling distribution of the sample range is 3. No, 80% of the possible values of the range of the samples is less than 3. No, the mean of the sampling distribution of the sample ranges is 1.6, which is not 3. Unmark this question Save and Exit Next entViewers/AssessmentViewer/Activit Submit
