Question

A manufacturer wishes to determine the effectiveness of four types of machines, A, B, C, D, in the production of bolts. To accomplish this, the number of defective bolts produced by each machine on the days of a given week are obtained for each of the two shifts. The results are indicated in the table below. Perform an analysis of variance to test at the 0.05 level of significance whether there is (a) a difference in machines, (b) a difference in shifts.
