ANOVA table
Post hoc analysis
Tukey simultaneous comparison t-values
The Excel/MegaStat output given above summarizes the results of a one-way analysis of variance in an attempt to compare the performance characteristics of four brands of vacuum cleaners. The response variable is the amount of time it takes to clean a specific size room with a specific amount of dirt.
Use the information above and determine a Tukey simultaneous 95 percent confidence interval for μ₁ − μ₂. The mean and sample sizes for brand 1 and brand 2 are as follows: = 2.95, = 2.28, n₁ = 4, and n₂ = 5.
