New York publishing company

An editor of a New York publishing company claims that the mean time taken to write a textbook is at least 31 months. A sample of 16 textbook authors found that the mean time taken by them to write a textbook was 25 months with a standard deviation of 7.2 months.

a. Using the 2.5% significance level, would you conclude that the editor’s claim is true? Assume that the time taken to write a textbook is normally distributed for all textbook authors.

b. What is the Type I error in part a? What is the probability of making this error?

c. What will your decision be in part a if the probability of making a Type I error is .001?
