A group of students estimated the length of one minute without reference to a watch or​ clock, and the times​ (seconds) are listed below. Use a 0.01 significance level to test the claim that these times are from a population with a mean equal to 60 seconds. Does it appear that students are reasonably good at estimating one​ minute? 76 89 46 77 52 35 71 73 72 60 70 80 105 97 77   Assuming all conditions for conducting a hypothesis test are​ met, what are the null and alternative​ hypotheses?   1. What is the test static? 2. What is the P- Value? 3. Conclusion (reject or fail to reject and why)?
