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 always 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 workors

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 always
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.

Carry out an appropriate statistical analysis using alpha=D0.001
a) What is the probability value for the null hypothesis being correct?
b) Which shift is better Rotating Shift or Fixed Shift and Why
c) On the two graphs below draw what you think the distribution of values
around the mean for Rotating Shift and Fixed Shift would look like.
