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
Type B:
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.
