The table to the right shows the cost per ounce (in dollars) for a random sample of toothpastes exhibiting very goodstain removal, good stain removal, and fair stain removal. At a = 0.025, can you conclude that the mean costs perounce are different? Perform a one-way ANOVA test by completing parts a through d.
