Listed below are the top 10 annual salaries (in millions of dollars) of TV personalities. Find the range, variance, and standard deviation for the sample data. Given that these are the top 10 salaries, do we know anything about the variation of salaries of TV personalities in general? 42 41 39 31 23 21 18 17 16.8 16.1 O ... The range of the sample data is $ million. (Type an integer or a decimal.) The variance of the sample data is (Round to two decimal places as needed.) The standard deviation of the sample data is $ (Round to two decimal places as needed.) million. Is the standard deviation of the sample a good estimate of the variation of salaries of TV personalities in general? O A. No, because there is an outlier in the sample data. O B. Yes, because the sample is random. OC. No, because the sample is not representative of the whole population. O D. Yes, because the standard deviation is an unbiased estimator.

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: - 2.00, - 1.00, 0, 1.00, 2.00? Why? O A. Thez score of 1.00 is most preferable because it is 1.00 standard deviation above the mean and would correspond to an above average test score. O B. The z score of - 2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. O C. The z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. O D. The z score of 0 is most preferable because it corresponds to a test score equal to the mean. OE. The z score of 1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average test score. Next
