4. The following table shows the calculated sums of squares and associated degrees of freedom. Complete the analysis of variance table and analyze the results of this experiment DEGREES OF FREEDOM SOURCE OF VARIATION Task Worker type Interaction SUM OF SQUARES 62.04 0.06 1.85 23.31 87.26 Error Total 63 66 Hint: To calculate the F test, you should consider factors (Task, Worker type and Interaction) one by one with Error. The first test is Task and Error. The second test is Worker type and Error, and the last test is Interaction and Error
