The frequency distribution shows the ages for a sample of 100 employees. Find the expected frequencies for each class to determine if the employee ages are normally distributed. Class boundaries 29.5-39.5 Frequency, f 14 39.5-49.5 29 49.5-59.5 31 59.5-69.5 18 69.5-79.5 A 10, 25, 33, 22, and 6, respectively. B 17, 32, 30, 15, and 9, respectively. C 18, 33, 29, 14, and 10, respectively. D 11, 26, 32, 21, and 7, respectively. The frequency distribution shows the ages for a sample of 100 employees.
