TABLE 10-18
As part of an evaluation program, a sporting goods retailer wanted to compare the downhill coasting speeds of four brands of bicycles. She took three of each brand and determined their maximum downhill speeds. The results are presented in miles per hour in the table below

-Referring to Table 10-18, based on the Tukey-Kramer procedure with an overall level of significance of 0.05, the retailer would decide that the three means other than the mean for Tornado are not significantly different from each other.

Quizplus · Accepted Answer

The table does not provide enough information for us to calculate the result of the Tukey-Kramer procedure. However, the question states that the overall level of significance is 0.05, which is a common significance level used in statistical tests. If the Tukey-Kramer test resulted in the decision that the three means other than Tornado are not significantly different, this means that they are statistically similar and cannot be distinguished from each other. Therefore, the correct answer is A) True.
