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.

Step 1
Since we are testing the claim that the mean is equal to 60 seconds, our null hypothesis will be that the mean is equal to 60 seconds, and the alternative hypothesis will be that the mean is not equal to 60 seconds. Null hypothesis (Hā): Ī¼ = 60 Show moreā¦

A group of students estimated the length of one minute without reference to a watch or clock, and the times in 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 the students are reasonably good at estimating one minute? What are the null and alternative hypotheses? Ho: Ī¼ = 60 seconds H1: Ī¼ ā 60 seconds Determine the test statistic: 0.61 (Round to two decimal places as needed) Determine the P-value: 0.550 (Round to three decimal places as needed) State the final conclusion that addresses the original claim: Fail to reject Ho. There is not sufficient evidence to conclude that the original claim that the mean of the population of estimates is 60 seconds is not correct. It appears that, as a group, the students are reasonably good at estimating one minute.

A. H0: Ī¼ ā 60 seconds, H1: Ī¼ = 60 seconds B. H0: Ī¼ = 60 seconds, H1: Ī¼ > 60 seconds C. H0: Ī¼ = 60 seconds, H1: Ī¼ ā 60 seconds D. H0: Ī¼ = 60 seconds, H1: Ī¼ < 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. H0. There is evidence to conclude that the original claim that the mean of the population of estimates is 60 seconds correct. It that, as a group, the students are reasonably good at estimating one minute.
