Very good The table to the right shows the cost per ounce (in dollars) for a random sample of toothpastes exhibiting very good stain removal, good stain removal, and fair stain removal. At a = 0.025, 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 stain removal re 0.35 same variances. 0.49 0.36 1.44 0.47 0.33 .....

(claim) O D. Ho: H1 = H2 = H3 (claim) Ha: At least one mean is different from the others.
