3. Research Problem: Job satisfaction as a function of work schedule was investigated in two diferent factories. In the first factory the employees are on a fixed shift system while in the second factory the workers have a rotating shift system. Under the fixed shift system, a worker ahvays works the same shift, while under the rotating shift system, a worker rotates through the three shifts. Using the scores below determine if there is a significant difference in job satisfaction between the two groups of workers.

3. Research Problem Job satisfaction as a function of work schedule waS investigated in two different factories. In the first factory the employees are on a fixed shift system while in the second factory the workers have a rotating shift system. Under the fixed shift system, a worker ahways works the same shift, while under the rotating shift system, 8 worker rotates through the three shifts. Using the scores below determine if there is a significant difference in job satisfaction between the two groups of workers. Work Satisfaction Scores for Two Groups of Workers Rotating Shift 63 71 48 57 53 48 57 76 52 68 Fixed Shift 79 83 68 59 81 76 80 74 58 49 68 Carry out an sppropriate statistical analysis using alpha=D0.001 and complete the table: Rotating Shift Fixed Shift t Stat P(T<-1) two-tal t Critical two-tail d) What is the probability value for the null hypothesis being correct? e) What is the alternative hypothesis f What is your conclusion with two reasons? g) Which shift is better Rotating Shift or Fixed Shift and Why h) On the two graphs below draw what you think the distribution of values arounc the mean for Rotating Shift snd Fixed Shift wou d look lke
