Independent random samples from normal populations produced the results shown below. Assume the variance of the two samples are the same. Sample 1: 5.9, 5.0, 3.8, 4.6, 5.2 Sample 2: 4.4, 6.1, 5.2, 5.7 (1) Can we conclude that 1 is less than 42 by more than 1 using a = .10. (2) Use P-value method to perform above hypothesis at a = .20 (3) Find a 90% confidence interval for (1-2) for a two-sided interval.
