The time to complete the Advanced Placement (AP) Statistics Exam in previous years is normally distributed with an average time of 2.4 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 26 students that took the exam and their mean time was 2.75 hours with a standard deviation of 0.35 hours. Test to see if the mean time has significantly changed using a 5% level of significance. Give answers to at least 4 decimal places.

What are the correct hypotheses? H₀: Select an answer s p s p x ? = < > hours H₁: Select an answer p p x s s ? > = < hours Using technology, conduct the hypothesis test and answer the following correctly:

The correct decision is to Select an answer Accept the alternative hypotheis Accept the null hypothesis Reject the null hypothesis Fail to reject the null hypothesis . The correct summary would be: Select an answer There is enough evidence to reject the claim There is enough evidence to support the claim There is not enough evidence to reject the claim There is not enough evidence to support the claim that the population mean time to complete the SAT has significantly changed from2.4 hours.
