In order to compare two tablet computers in respect to a planned purchase of several such tablets, a manager has 10 operators use each machine to perform a standard set of tasks. Randomly 5 operators were assigned machine A to test first while the other 5 tested machine S first. Then the operators changed to the other machine and did the test again. The time results are as follows: At the 5% level of significance test the null hypothesis that there is no difference between the average time to perform the required task on the two machines.
