The mathematics department at one university reports that the failure rate for College Alge is no more than 35% in any given semester. A group of students believes the rate is higher, and they decided to use a hypothesis test to see if they are correct. Based on the sample they obtain, they decided to reject the null hypothesis. If, in reality, the failure rate is 34%, did the students make an error? If so, what type?
