Given the sample data. x: 21, 17, 13, 30, 27 (a) Find the range. (Enter an exact number.) 17 (b) Verify that Ex = 108 and Ex2 = 2,528. (For each answer, enter an exact number.) EX = X Ex? = X (c) Use the results of part (b) and appropriate computation formulas to compute the sample variance s and sample standard deviation s. (For each answer, enter a number. Round your answers to two decimal places.) X S X (d) Use the defining formulas to compute the sample variance s and sample standard deviation s. (For each answer, enter a number. Round your answers to two decimal places.) $ 2 = X S = X (e) Suppose the given data comprise the entire population of all x values. Compute the population variance of and population standard deviation o. (For each answer, enter a number. Round your answers to two decimal places.) 02 = 0 = X Enter a number Need Help? Read It Submit
