See attached for my question to Math 222 7.3.16 image text in transcribed 7.3.16 How many calories do you think you burn or expend with 60 minutes of walking on the treadmill? An article that appeared in the American Journal of Men's Health (2010) presented the results of a study conducted by researchers Harris and George, whose objective was to evaluate how accurately men can estimate their energy expenditure (EE) as measured in kilocalories (kcal). 100 normal-weight and overweight male participants, ages 21-45 years, were recruited from a large, urban university in South Florida. During one session, each participant was made to walk for 60 minutes on a treadmill, and their actual EE was calculated. After they had completed the task, each participant was asked to estimate the number of calories they burned during the task. Here are some summary statistics. Sample Sample Sample size average (kcal) SD (kcal) Estimated 100 xe = 370 se = 455.1 Actual 100 xa = 244 sa = 40.2 Difference = 100 Estimated - Actual xd = 126 sd = 354.2 Don't show me this message again for the assignment Your answer is incorrect.

Try again. The analysis you conducted in parts (a) is \"wrong\" since the data are paired. What do your results suggest about the effectiveness of pairing in this study? This suggests pairing was not effective at narrowing the focus of the study and drawing useful conclusions. This suggests pairing was not effective at reducing variability and improving strength of evidence against the null hypothesis.
