- Age 0-9: 43 * 4.5 = 193.5 - Age 10-19: 37 * 14.5 = 536.5 - Age 20-29: 41 * 24.5 = 1004.5 - Age 30-39: 66 * 34.5 = 2277 - Age 40-49: 69 * 44.5 = 3070.5 - Age 50-59: 47 * 54.5 = 2561.5 - Age 60-69: 31 * 64.5 = 1999.5 - Age 70-79: 13 * 74.5 = 968.5 - Age 80-89: 17 Show more…

find the mean of the data summarized in the given frequency distribution. Also, compare the computed means to theactual means obtained by using the original list of data values, which are as follows: (Exercise 29) 35.9 years; (Exercise 30) 44.1 years;(Exercise 31) 84.4; (Exercise 32) 15.0 years.
