question 97

Short Answer

SCENARIO 11-3
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 Scenario 11-3,what is the critical value of Levene's test for homogeneity of variances at a 5% level of significance?

Randomized Block Design

A statistical experimental design technique that involves grouping similar experimental units into blocks before randomly assigning treatments to the units within each block.

Treatments

Interventions or conditions that researchers apply to experimental units or subjects to measure their effect.

Levels

In the context of experimental design, refers to the different values that an experimental factor can take.

Randomized Block Design

An experimental design that groups subjects into blocks to account for variability among them and then randomly assigns treatments within those blocks.
