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 theseare the top 10 salaries, do we know anything about the variation of salaries of TVpersonalities in general?42 413931 2321181716.816.1 OThe 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.)millionIs the standard deviation of the sample a good estimate of the variation of salaries of TVpersonalities in general?O A. No, because there is an outlier in the sample data.B. Yes, because the sample is random.C. No, because the sample is not representative of the whole population.O D. Yes, because the standard deviation is an unbiased estimator.Next If your score on your next statistics test is converted to a z score, which of these zscores 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 deviationabove 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 deviationsbelow the mean and would correspond to the highest of the five differentpossible test scores.O C. The z score of 2.00 is most preferable because it is 2.00 standard deviationsabove the mean and would correspond to the highest of the five differentpossible test scores.O D. The z score of 0 is most preferable because it corresponds to a test scoreequal to the mean.OE. The z score of 1.00 is most preferable because it is 1.00 standard deviationbelow the mean and would correspond to an above average test score.Next
