PART A

The accuracy of verbal responses is tested in an experiment in which 16 subjects report their weight (lb) and they are then weighted on a physician's scale. The data consists of the reported weight and the measured weight for each subject. The summary statistics are given in the table below. Reported weight (1) To compare the reported weight and the measured weight, what hypothesis test should be used? Matched pairs t-test Independent samples z-test Independent samples t-test Test for two proportions Continue to consider Question 8. Find a 95% confidence interval for the difference of mean reported weight minus mean measured weight. O (-4.07, -1.93) O (-4.02, -1.98) O (-19.35, 13.35) O (-11.00, 5.00)Continue to consider Question 8. What can you conclude with 95% condence? The population mean reported weight is equal to the population mean measured weight. The population mean reported weight is less than the population mean measured weight. We are not sure if there is a difference between the population mean reported and measured weight. The population mean reported weight is greater than the population mean measured weight
