Analysts have determined that 12 of the 64 employees age 55 or older in the total work force were terminated.
a. Determine the probability that the sample proportion of age 55 or older employees who were terminated would be greater if employees were selected at random for termination.
b. Determine the probability that the sample proportion of age 55 or older employees who were terminated would be between .0625 and .125 if employees were selected at random for termination.
