Question
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
O B. Ho: u= 60 seconds
H: p#60 seconds
H:p>60 seconds
O C. Ho: H#60 seconds
O D. Ho: H = 60 seconds
H: p= 60 seconds
H: p<60 seconds
Determine the test statistic.
(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.
VHo- There is
evidence to conclude that the original claim that the mean of the population of estimates is 60 seconds
correct. It
V that, as a group, the students are reasonably good at estimating one minute.
