Use the results of the simulation study summarized in Table 7.4 to answer the following questions.
a. Which of skewness or heavy-tailedness appears to have the stronger effect on the F tests?
b. For a given population distribution, does increasing the sample size yield α values more nearly equal to the nominal value of .05? Justify your answer, and provide reasons why this may occur.
c. For the short-tailed distribution (uniform), the actual probability of Type I error is smaller than the specified value of .05. Provide both a negative and a positive impact on the F test of having a decrease in the specified value of α.
