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?   a. Determine the test statistic.   ​(Round to two decimal places as​ needed.)   b. Determine the​ P-value. ​(Round to three decimal places as​ needed.)
