2. Suppose there are two normally distributed populations. One population has variance of 12, and when a sample of size 22 was picked from it, the mean was 9. The second population has a variance of 14, and a sample of 18 yielded a mean of 7.8. Assume the samples are independent, at the 5 percent level of significance, test the null hypothesis Ho: u 1= 4 2 against the alternative hypothesis that u1> H2
