measured the amount of muscle (in percentage).
Men: 21.4. 15.0. 21.9. 20.0, 30.4, 22.0, 11.5, 21.4, 28.2, 22.4
Sample variance: 29.9
Women: 13.2. 6.0. 22.0, 9.0, 14.2, 18.5, 19.2, 22.4, 15.9, 22.5
Sample variance: 32.7
a) Test the hypothesis that the average musele percentage of women is less than men. Use the p-value method at a 90% confidence level.
