For the next set of questions, please complete the problems directly onto the space below. Investigators recruited SJSU college students trying to lose weight. Consenting participants were randomized into two groups. One group was assigned to low—intensity exercise for 1 hour per day, five days per week (N=300). The other group was assigned nothing (N=350). At the end of the 1 year study period, 250 in the low—intensity exercise group and 50 in the control group had lost weight. The average weight lost among 250 in the low—intensity exercise group was 4.6 pounds. The average weight lost among 50 in the control group was 1.3 pounds. N0 participants were lost to follow—up. A. What is the appropriate measure of frequency to use for this study design? 1pt B. Calculate the appropriate measure of frequency in the exposed group. Round to three decimals. 1pts C. Calculate the appropriate measure of frequency in the unexposed group. Round to three decimals. 1pts D. Calculate a ratio measure. Round to two decimals. 1pts E. Please interpret the ratio measure above. 1pt F. Calculate a difference measure. Round to two decimals. 1pt G. Please interpret the difference measure above. Express with multiplier of 100. 1pt H. Identify Population studied (Ecological or Individual), Timing, Type, Category, Design, Sub—design (if applicable) 3pts
