An article in Medicine and ScCience in Sports and Exercise "Maximal Leg-Strength Training Improves Cycling Econom in Previously Untrained Men," (2005, Vol. 37 pp. 131–1236) studied cycling performance before and after eight weeks of leg-strength training. Seven previously untrained males performed leg-strength training three days per week for eight weeks (with four sets of five replications at 85% of one repetition maximum). Peak power during incremental cycling increased to a mean of 315 watts with a standard deviation of 16 watts. Construct a 99% two sided confidence interval for the mean peak power after training. Assume population is approximately normally distributed. Round the answers to 2 decimal places.

An article in Medicine and Science in Sports and Exercise "Maximal Leg-Strength Training Improves Cycling Economy
in Previously Untrained Men," (2005, Vol. 37 pp. 131-1236) studied cycling performance before and after eight
weeks of leg-strength training. Seven previously untrained males performed leg-strength training three days per
week for eight weeks (with four sets of five replications at 85% of one repetition maximum). Peak power during
incremental cycling increased to a mean of 315 watts with a standard deviation of 16 watts. Construct a 99% two-
sided confidence interval for the mean peak power after training. Assume population is approximately normally
distributed.
Round the answers to 2 decimal places.
