The amount of time (in hours) needed to learn each of the three different brands is given below:

Below is the Excel output for the randomized block design:

-Referring to Table 11-8, the decision made at a 0.05 level of significance on the F test for the block effects implies that the blocking has been advantageous in reducing the experiment error.
