Solve the following:

9. We also measured the hight and body weight of 120 young women. The average hight was 165.3 cm, while the average weight was 65.4 kg. Suppose that the hight and weight follow 2-dimensional normal distribution with the above covariance matrix C. Test the zero hipothesis that the hight and weight of young men and women do not differ significantly (choose 95% for the level of confidence)!
