TABLE 11-8
An important factor in selecting database software is the time required for a user to learn how to use the system.To evaluate three potential brands (A,B and C)of database software,a company designed a test involving five different employees.To reduce variability due to differences among employees,each of the five employees is trained on each of the three different brands.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:
-True or False: 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.

Quizplus · Accepted Answer

The F test for the block effects has a p-value of 0.078, which is greater than the significance level of 0.05. Therefore, we fail to reject the null hypothesis that the block effects are not significant. This implies that blocking has not been advantageous in reducing the experiment error.
