In the following situation we want to compare the mean responses in several populations It is generally accepted that regular exercise provides health benefits to individuals with type 2 diabetes, although the exact exercise regimen aerobic vs. resistance vs. both) is unclear. The subjects in this study were sedentary 30- to 75-year-old adults with type 2 diabetes and elevated hemoglobin A1c levels above 6.5%. The level of hemoglobin A1c correlates very well with a person's recent overall blood sugar levels. If the blood sugars have generally been running high during the previous few months, the level of hemoglobin A1c will be high. In a randomized controlled study, 41 subjects were assigned to a nonexercise control group, 75 to resistance training only, 74 to aerobic exercise only, and 76 to combined aerobic and resistance training. The weekly duration of exercise was similar for all three exercise groups, and subjects remained on the exercise regimens for nine months. At the end of nine months, the hemoglobin Alc levels of subjects were measured.
Identify the populations and the response variable. Then give I, the ni, and N. Finally, give the degrees of freedom of the ANOVA Fstatistic. Populations
A. combined aerobic and resistance training
B. control (sedentary), aerobic exercise, resistance training, combined aerobic and resistance training control (sedentary)
C. A1c level O resistance training, aerobic exercise, and Alc level Response variable
D. resistance training
E. control (sedentary)
F. combined aerobic and resistance training
G. A1c level aerobic exercise control nresistance E aerobic combined
