Question: 6.22. Example 6.4 (page 151) tested a therapy for anorexia, using Hq'. ^ = 0 and Ha'. p, > 0 about the population mean weight

6.22. Example 6.4 (page 151) tested a therapy for anorexia, using Hq'. ^ = 0 and Ha'. p, > 0 about the population mean weight change.

(a) In the words of that example, what would be a (i) Type I error, (ii) Type II error?

(b) The P-value was 0.017. If the decision for a =

0.05 were in error, what type of error is it?
