The time to complete the Advanced Placement (AP) Statistics Exam in previous years is normally distributed with an average time of 2.5 hours. Because of school closures due to COVID-19, the College Board offered an at-home test for the 2020 AP Statistics Exam. A teacher feels that students, on average, will have a different completion time for the at-home exam. They take a random sample of 28 students that took the exam and their mean time was 2.65 hours with a standard deviation of 0.3 hours. Test to see if the mean time has significantly changed using a 10% level of significance. Give answers to at least 4 decimal places. What are the correct hypotheses?
