Question
5.21 A study was conducted of 90 adult male patients following a new treatment for congestive heart failure. One of the variables measured on the patients was the increase in exercise capacity (in minutes) over a 4-week treatment period. The previous treatment regime had produced an average increase of u = 2 minutes. The researchers wanted to evaluate whether the new treatment had increased the value of u in comparison to the previous treatment. The data yielded y = 2.17 and s = 1.05. a. Using a = .05, what conclusions can you draw about the research hypothesis? b. What is the probability of making a Type II error if the actual value of u is 2.1?
