Chapter 4, Section 5, Exercise 160
Hypotheses for a statistical test are given, followed by several
possible confidence intervals for different samples. In each case,
use the confidence interval to state a conclusion of the test for
that sample and give the significance level used. In addition, in
each case for which the results are significant, state which group
(1 or 2) has the larger mean.
Hypotheses: H0:μ1=μ2 vs Ha:μ1≠μ2
(a) 95% confidence interval for μ1-μ2: 0.15 to 0.55
Conclusion:...
