One-Koat Paint Company has developed a new type of porch paint that it hopes will be the most durable on the market. The R&D group tests the new product against the two leading competing products by using a machine that scrubs until it wears through the coating. One-Koat runs five trials with each products and secures the following results (in thousands of scrubs):

Trial	One-Koat	Competitor A	Competitor B
1	37	34	24
2	30	19	25
3	34	22	23
4	28	31	20
5	29	27	20

Test the hypothesis that there are no differences between the means of these products (α = .05).
