We have good reason to suspect that the mean number of hours worked per week by software developers, μ, is now greater than 44 and wish to do a statistical test. We select a random sample of software developers and find that the mean of the sample is 48 hours and that the standard deviation is 6 hours. Based on this information, complete the parts below. (a) What are the null hypothesis H0 and the alternative hypothesis H1 that should be used for the test? (b) Suppose that we decide to reject the null hypothesis. What sort of error might we be making? (c) Suppose the true mean number of hours worked by software engineers is 50 hours. A Type II error would be _____ the hypothesis that μ is_____ when, in fact, μ is_____ .
