The student body at many community colleges is considered a "commuter population". The following question was asked of the Student Affairs Office at one such college: "How far (one way) does the average community college student commute to college daily?" The office answered: "20.0 miles or less." The inquirer was not convinced of the truth of this and decided to test the statement. She took a random sample of 55 students and found a mean commuting distance of 21.5 miles. Test the statement made by the Students affairs Office at a significance level of 0.01. Assume that the population standard deviation is known to be 5.1 miles. Use the P-Value Method of Testing. 1. The null hypothesis, Ho 2. The alternative hypothesis, H1 3. The test statistic 4. The type of test(left, right, two-tailed) and the p-value 5. The decision to accept Ho or reject Ho
