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? 75 88 51 73 49 31 69 74 72 59 72 81 99 101 73 What are the null and alternative hypotheses? A. Upper H 0: muequals60 seconds Upper H 1: munot equals60 seconds B. Upper H 0: munot equals60 seconds Upper H 1: muequals60 seconds C. Upper H 0: muequals60 seconds Upper H 1: muless than60 seconds D. Upper H 0: muequals60 seconds Upper H 1: mugreater than60 seconds Determine the test statistic. nothing (Round to two decimal places as needed.) Determine the P-value. nothing (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. ▼ Fail to reject Reject Upper H 0. There is ▼ sufficient not sufficient evidence to conclude that the original claim that the mean of the population of estimates is 60 seconds ▼ is is not correct. It ▼ appears does not appear that, as a group, the students are reasonably good at estimating one minute.
