6. CI for Differences in Means: Randomly sample 100 observations from N(2,200) and 100 observations from N(2.2,121) and assume you did not know the true populations of N(2,200) and N(2.2,121). Using the difference your first and second sample means, X, - X, and the standard deviations of the difference, find a 95% confidence n2 interval (upper and lower bounds) for the difference between the first and the second pop- ulation means, µj - H2.

6. CI for Differences in Means: Randomly sample 100 observations from N(2,200) and 100 observations from N(2.2,121) and assume you did not know the true populations of N(2,200) and N(2.2,121). Using the difference your first and second sample means, X - X, and the standard deviations of the difference, find a 95% confidence n2 + interval (upper and lower bounds) for the difference between the first and the second pop- ulation means, µj - H2.
