TABLE 11-6
As part of an evaluation program, a sporting goods retailer wanted to compare the downhill coasting speeds of 4 brands of bicycles. She took 3 of each brand and determined their maximum downhill speeds. The results are presented in miles per hour in the table below.

-Referring to Table 11-6, what should be the decision for the Levene's test for homogeneity of variances at a 5% level of significance?
A) Reject the null hypothesis because the p-value is smaller than the level of significance.
B) Reject the null hypothesis because the p-value is larger than the level of significance.
C) Do not eject the null hypothesis because the p-value is smaller than the level of significance.
D) Do not reject the null hypothesis because the p-value is larger than the level of significance.

Quizplus · Accepted Answer

The p-value for Levene's test is 0.47, which is larger than the level of significance of 0.05. Therefore, we do not have enough evidence to reject the null hypothesis of equal variances.
