The chi-square goodness-of-fit test is used to test whether the observed frequency distribution of a variable fits a expected frequency distribution. In this case, we have observed frequencies (number of times each face appeared) and an expected frequency distribution would be a fair die with each face appearing equally likely (i.e., 1/6 of the time). We can use the chi-square goodness-of-fit test to determine whether the observed frequencies deviate significantly from what we would expect for a fair die. Therefore, the best choice is B.
