In a one-way ANOVA model with k = 3 groups and 4 observations per group: (a) Use the F-statistic in Model Reduction Method 2 to derive a statistic for testing whether the average of the means of the first two groups is the same for the mean of the third group. That is, create the F-statistic for testing H0 : (μ1+μ2)/2 = μ3. (Hint: Don’t fit a model with a y-intercept. It makes everything easier.) (b) Where μ1ˆ = 5.6,...

exercise and the tukey hsd test: in how it works 11.1, we conducted a one-way between-groups anova on an abbreviated data set from research by irwin and colleagues (2004) on adherence to an exercise regimen. Participants were asked to attend a monthly group education program to help them change their exercise behavior. Attendance was taken and participants were divided into three categories: those who attended fewer than 5 sessions, those who attended between 5 and 8 sessions, and those who...

In a market research study, members of a consumer test panel are asked to rate the visual appeal (on a 1 to 10 scale) of the texture of dashboard plastic trim in a mockup of a new fuel cell car. The manufacturer is testing four finish textures. Panelists are assigned randomly to evaluate each texture. The test results are shown below. Each cell shows the average rating by panelists who evaluated each texture. Research question: Is mean rating affected by...
