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.

For the last part the options are:
FAIL TO REJECT or REJECT; SUFFICIENT or NOT SUFFICIENT; IS or IS NOT; DOES NOT APPEAR or APPEARS.
Expert Solution
Step 1
In this case, the population standard deviation is not given. In addition, the sample size is not large enough. Hence, one sample t test is used.
