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 0.0 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? 77 93 49 71 51 32 71 72 78 56...
