Test a claim that the difference in the time to walk up the boardwalk and the time to walk the boardwalk is not zero. The data for this is here. Take alpha to be 0.05. Construct and interpret a 95% confidence interval for the mean difference of the population means. Please include a zero to the left of the decimal where appropriate and round all answers to the nearest thousandths place... three places to the right of the decimal. Confidence interval lower bound: [answer1] Confidence interval upper bound: [answer2] Interpretation... choose the appropriate interpretation and enter the corresponding capital letter: A We are 95% confidence that the population mean lies in the interval. B We are 95% confident that a randomly chosen data point difference will fall between the boundaries. C We are 95% confident that all of the data differences will fall between the boundaries. D We are 95% confident that all of the data will fall between the boundaries. E We are 95% confidence that the difference of the population means lies in the interval. [Answer5] A second interpretation of this confidence interval would be... choose the appropriate interpretation and enter the corresponding capital letter: A The population mean time to walk up the boardwalk is greater than the population mean time to walk down the boardwalk B The population mean time to walk up the boardwalk is less than the population mean time to walk down the boardwalk C The population mean time to walk up the boardwalk and the population mean time to walk down the boardwalk are the same [Answer6] Suppose a t-test was used to test a claim that the difference in the time to walk up the boardwalk and the time to walk the boardwalk is not zero. The data for this is here. Take alpha to be 0.05. Set up the hypotheses to test the claim... choose the appropriate interpretation and enter the corresponding capital letter: A
