To determine whether the "one" side on a commercially manufactured die is heavy and the "six" side is light, a student kept track of the number of observed 1s when observing 8000 rolls of the dice. Let p denote the probability of rolling a one with such a die. The student would like to test the null hypothesis that the die is fair. a.Define the null and alternative hypotheses, test statistic and the decision rule for this test. b.If y=1265 ones were observed in 8000 rolls, calculate the value of the test statistic and state your conclusion
