A workout coach believes that walking every day can produce the same health benefits as jogging. Ten volunteers are paired based on significant characteristics, and half of the group is asked to walk every day and half of the group is asked to jog every day. The amounts of weight lost (in pounds) over a 30-day period are recorded in the following table. Construct a 98% confidence interval for the true mean difference between the amount of weight lost by jogging and the amount of weight lost by walking. Assume that the population distribution of the paired differences is approximately normal. Round to one decimal place. Weight Loss (in pounds) Pair 1 2 3 4 5 Walking 10 12 11 12 9 Jogging 15 17 16 17 12
