Question 1 (6 points) Two college instructors are interested in whether or not there is any variation in the way they grade math exams. They each grade the same set of 10 exams. The first instructor's grades have a variance of 59.2. The second instructor's grades have a variance of 72.5. Test the claim that the first instructor's variance is smaller. (In most colleges, it is desirable for the variances of exam grades to be...

3. The table to the right shows the cost per ounce (in dollars) for a random sample of toothpastes exhibiting very good stain removal, goad stain removal, and fair stain removal. At α= 0.01, can you conclude that the mean costs per ounce are different? Perform a one-way ANOVA test by completing parts a through d. Assume that each sample is drawn from a normal population, that the samples are independent of each other, and that the populations have the...
