4.160  

Hypotheses: H0 : μ1 = μ2 vs Ha : μ1 ≠ μ2. In addition, in each case for which the results are significant, state which group (1 or 2) has the larger mean.

(a) 95% confidence interval for μ1 − μ2 : 0.12 to 0.54

(b) 99% confidence interval for μ1 − μ2 : −2.1 to 5.4

(c) 90% confidence interval for μ1 − μ2 : − 10.8 to −3.7
