Consider the data from Exercise 6.S.20(a) which led to a 95% confidence interval for μ1, - μ2 of (-2.3,16.1).
(a) True or false (and say why)^We are 95% confident that the difference between 1 and 2 is between -2.3 days and 16.1 days.
(b) True or false (and say why): If this experiment were repeated many times (with the same sample sizes), then 95% of the time 1- 2 would be between -2.3 and 16.1.
(c) True or false (and say why): We are 95% confident that nitric oxide has no effect on the mean length of hospitalization because zero is in the confidence interval.
