Fill out the following table: Table 1: ANOVA Table Df SS MS F p-value Treatment 2 ? ? ? 0.0003 Residual ? 642.8 ? Total 31 1126.04 ? 1. How many groups must there be? 2. How many total subjects must there be? MST MSE 3. What specific distribution does have under the null hypothesis? 4. Do large or small values of F provide evidence against the null hypothesis? 5. This is the ANOVA table when testing whether the average miles per gallon (mpg) of a vehicle is dependent upon its number of forward gears (gear). Access the data by typing "attach(mtcars)" into R. Provide the R code which verifies your entries in the ANOVA table. 6. State the null and alternative hypotheses in the context of this problem. Ho: Ha: 7. At the 0.001 significance level, is there evidence that the average mpg of a vehicle differs based upon its num- ber of forward gears? 8. Are the assumptions satisfied?
