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 lo 60 seconds. Does it appear that students are reasonably good at estimating one minute? 69 80 40 67 40 27 58 65 66 45 67 68 95 88 66 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. H9: H60 seconds H:H 60 seconds O B. Ho: H= 60 seconds H:> 60 seconds O C. Ho: 60 seconds O D. Ho: u60 seconds H:= 60 seconds H:u< 60 seconds

The display provided from technology available below results from using data for a smartphone carrier's data speeds at airports to test the claim that they are from a population having a mean less f than 4.00 Mbps. Conduct the hypothesis test using these results. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.
