The average manufacturing work week in metropolitan Chattanooga was 40.1 hours last year. It is believed that the recession has led to a reduction in the average work week. To test the validity of this belief that the mean hours worked has dipped below 40.1 hours, the hypotheses are (hint…start with the alternative hypothesis as being the belief that you are testing): a. H0: µ ≥ 40.1; H1: µ < 40.1 b. H0: µ < 40.1; H1: µ ≥ 40.1 c. H0: µ > 40.1; H1: µ ≤ 40.1 d. H0: µ = 40.1; H1: µ ≠ 40.1
