Example Two different processes (Type A and Type B) are used to produce

tinplate. The following values show the weights of samples produced

by each process.

Type A: 105 108 86 103 103 107 124 124

Type B: 89 92 84 97 103 107 111 97

Using the level of significance 0.05, test the null hypothesis that the

tinplate produced by the two processes are of the same level.

Since P = 0.08602732 > 0.05 (level of significance), we can not reject the null hypothesis

and conclude that the tinplate produced by the two processes are of the same level.
