Question

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 0.10 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? 

71 79 39 63 41 27 59 66 68 46 66 72 91 87 63 

What are the null and alternative hypotheses?
