The exercise hours dataset contains information on the amount of exercise (hours per week) for a sample of statistics students. The mean amount of exercise was 9.4 hours for the 30 male students in the sample and 12.4 hours for the 20 female students. The randomization distribution of differences in means based on these data normally distributed. The standard error for the difference in means, as estimated from the randomization distribution is SE-2.38. Use this information to test at 5% significant level, whether the data show that the mean exercise time for female students is less than the mean exercise time of male students.
