I need some help with this problem, I feel like this should be correct? Unless I missed something

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 ve 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 condence interval for the mean peak power after training. Assume population is approximately normally distributed. Round the answers to 2 decimal places. :i 295.99 5 H S i 334.01
