At a = 0.05, 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 same variances. stain stain removal removal removal 0.64 2.66 0.35 0.60 0.64 1.32 0.36 1.59 0.98 0.58 0.44 0.37 0.33 0.47 1.39 (a) Identify the claim and state Ho and H.

The critical value is Fo
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= 0.05, 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 same variances.
