A study wished to examine the resting heart rate of two different types of athletes, those who use mainly anaerobic techniques and those who use aerobic techniques. Group 1 contained 400 weight lifters who had a mean resting heart rate of 65 bpm with a standard deviation of 12 bpm. Group 2 contained 400 long distance runners who had a mean resting heart rate of 57 bpm and a standard deviation of 9 bpm. Construct a 95% CI around the difference in mean resting heart rate between the two groups.
