Assume that the populations in the problem all follow normal distributions. (a) The following are the Brinell hardness values obtained for samples of two alloys A and B: A 66.3 63.5 64.9 61.8 64.3 64.7 65.1 64.5 68.4 63.2 B 71.3 60.4 62.6 63.9 68.8 70.1 64.8 68.9 65.8 66.2 Use the 0.05 level of significance to test the null hypothesis that A and B have the same average hardness values against the alternative hypothesis A has a smaller hardness value than B.
