Students estimated the length of one minute without reference to a watch or clock, and the times (seconds) are listed below. Assume that a simple random sample has been selected. Use a 0.01 signicance 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? Perform the test assuming that the requirements are met. Identify the null and alternative hypotheses. Ho: iv v H1: '7 7 (Type integers or decimals. Do not round.) Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) State the conclusion about the null hypothesis, as well as the nal conclusion that addresses the original claim. Decide whether it appears that students are reasonably good at estimating one minute. the null hypothesis. There 7 sufcient evidence at the 0.01 signicance level to '7 the claim that the times are from a population with a mean equal to 60 seconds; on this basis it V that as a group the students are reasonably good at estimating one minute.
