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?

Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?
O A. Ho H= 60 seconds
H: µ# 60 seconds
O B. Ho: = 60 seconds
H: u<60 seconds
O D. Ho: ut 60 seconds
O C. Ho H=60 seconds
H1 p> 60 seconds
H,: u= 60 seconds
Determine the test statistic.
O (Round to two decimal places as needed.)
Determine the P-value.
(Round to three decimal places as needed.)
State the final conclusion that addresses the original claim.
V Ho. There is
V evidence to conclude that the mean of the population of estimates is 60 seconds
V correct. It
that, as a group, the students are reasonably
good at estimating one minute.
