A crayon manufacturer is comparing the effects of two kinds of yellow dye on the brittleness of crayons. Dye B is more expensive than dye A, but it is thought that it might produce a stronger crayon. Four crayons are tested with each kind of dye, and the impact strength (in joules) is measured for each. The results are as follows: Dye A: 1.3 2.0 1.2 3.0 Dye B: 3.0 3.2 2.9 3.4 Can you conclude that the mean strength of crayons made with dye B is greater than that of crayons made with dye A? Compute the P-value and state a conclusion. Since , we conclude that the mean strength of crayons made with dye B is greater than that made with dye A.
