Question Answered step-by-step Twenty-two women between the ages of 70 and 80 were randomly… Twenty-two women between the ages of 70 and 80 were randomly selected from the general population of women in this age group to take part in a special program to decrease reaction time (speed). After the course, the women had an average reaction time of 2.0 seconds. Assume that the mean reaction time for the general population of women in this age group is 2.1, with a standard deviation of 0.4 seconds. (Assume that the population is approximately normal). a.)
