The hypothesis test is to be conducted at the significance level
of 5% to see if the population average of the principal component A
content of the two products (trademark 1, trademark 2) is the same.
The sample data of the main ingredients of trademark 1 and
trademark 2 are as follows. (1) Test whether each data follows a
normal distribution. (2) Test whether the mother variance is the
same. (3) Test whether the population mean is equal. By using
program R.
