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 98% two-sided confidence interval for the mean peak power after training. Assume
population is approximately normally distributed.
Round the answers to 2 decimal places.
