Question 28 A data set contains the following seven values. 13 5 8 16 2 7 9 (Round the intermediate values to 4 decimal places.) a. Find the range. 13 b. Find the mean absolute deviation. (Round your answer to 4 decimal places.) c. Find the population variance. (Round your answer to 4 decimal places.) d. Find the population standard deviation. (Round your answer to 4 decimal places.) e. Find the interquartile range. f. Find the z score for each value. (Round your answers to 2 decimal places) z score for 13 = z score for 5 = z score for 8 = z score for 16 = z score for 2 = z score for 7 = z score for 9 =
