ty-nive women between the ages of 70 and were randomly selected from the general pop tion of women their age to take part in a special program to decrease reaction time (speed). After the course, the women had an average reaction time of 688 milliseconds. Assume that the mean reaction time for the general population of women of this age group is 700 milliseconds with a standard deviation of 300 milliseconds. (a) Compute a 95% confidence interval for u, the population mean reaction time for women who have taken part in the program. (b) Perform a hypothesis test to decide whether the course had a significant effect on reaction times.
