Question: A somewhat outdated study indicates that the mean number of hours worked per week by software developers is 44. We have good reason to suspect

A somewhat outdated study indicates that the mean number of hours worked per week by software developers is 44. We have good reason to suspect that the mean number of hours worked per week by software developers, p, is now greater than 44 and wish to do a statistical test. We select a random sample of software developers and nd that the mean of the sample is 49 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? H0: EIEI H1: Elan EI=EI Eben (b) Suppose that we decide not to reject the null hypothesis. what sort of error might we be making? (Choose one) Y X b (C) Suppose the true mean number of hours worked by software engineers is 51 hours. Fill in the blanks to describe a Type II error. A Type [I error would be the hypothesis that p is (Choose one) Y when, in fact, p is
