Given the sample data. x: 23, 17, 15, 30, 27 (a) Find the range. (Enter an exact number.) 15 (b) Verify that 2x = 112 and 2x2 = 2,672. (For each answer, enter an exact number.) 2x = 112 J 2x2 = 2672 (c) Use the results of part (b) and appropriate computation formulas to compute the sample variance 52 and sample standard deviation 5. (For each answer, enter a number. Round your answers to two decimal places.) 52 = 32.64 x s = 5.71 x ll (d) Use the defining formulas to compute the sample variance 52 and sample standard deviation 5. (For each answer, enter a number. Round your answers to two decimal places.) 52 = 40.80 5 = 6.387 y 2 (e) Suppose the given data comprise the entire population of all x values. Compute the population variance 0' and population standard deviation 0'. (For each answer, enter a number. Round your answers to two decimal places.) 0'2 = 32.64 I Need Help? 0-: l:I NI _
