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 0.05 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? 66, 79, 39, 65, 41, 26, 58, 62, 68, 47, 63 73, 91, 87, 68. 1. Determine the test statistic 2. P-value 3. State the final conclusion that addresses the original claim.

Given:-
66,79,39,65,41,26,58,62,68,47,63,73,91,87,68
significance leve
population mean = 60
we have to calculate the test statistic , P-value , State the final conclusion that addresses the original claim.
1.
the mean is the sum of all values divided by the number of values
so,
the variance is the sum of squared deviation from the mean divided by ( n-1 ) . The standard deviation is the square root of the variance
