Question

1. Finally, the researchers are interested in whether workplace cohesion attitudes change, as employees move from sub-optimal working conditions to above average working conditions. They collect data from the same employees, first when working under sub-optimal conditions and then one month after moving to above average conditions. Test for this hypothesis based on the new data below.

                                                Sub-standard   Above average       Difference (sub-above)

x    80.00 76.00 4.00

                     s 6.00 8.00 3.00

                     n   40.00 36.00 36.00

Type of test: ___________________________________________________________
