A study is published with information about ages of people in a particular region. A sample of fNe ISidents fom the gion lave the 30 66 56 28 45 a. Determine the range of these ages. The range isO (Simplify your answer.) Σ b. Find the sample standard deviation of these ages by using the defining formula s= where n is the sample size and x is the sample mean. n-1 The standard deviation isO (Round to one decimal place as needed) E -(Ex)°/n where n is the sample size. c. Find the sample standard deviation of these ages by using the computing formula s= n-1

Question
A study is published with information about ages of people in a particular region. A sample of five residents from the region have the following ages, in years. Complete parts (a) through (d) below. 30 66 56 28 45 a. Determine the range of these ages. The range is (Simplify your answer.) E(x-) where n is the sample size and x is the sample mean. b. Find the sample standard deviation of these ages by using the defining formula s= n-1 The standard deviation is (Round to one decimal place as needed.) E-(Ex)°/n where n is the sample size. c. Find the sample standard deviation of these ages by using the computing formula s= n-1 The standard deviation is (Round to one decimal place as needed.) d. Compare vour work in parts (b) and (c)
