A claim is made that the average number of credits enrolled in during spring semester by OSU undergraduates is 12. You believe this claim is incorrect, so you decided to conduct a hypothesis test, with a two-tailed (or two-sided) alternative hypothesis. Upon gathering data from a random sample of students, you obtain a test statistic of 2.4. If we assume the significance (or alpha) level is 0.01, what should your decision be? Reject the null hypothesis O Fail to reject the alternative hypothesis O Reject the alternative hypothesis O Fail to reject the null hypothesis
