al| 25%< TitleA physical education professor believes thatexercise can slow the aging process. For thepast 10 years, he has been conducting anexercise class for 14 individuals who arecurrently 50 years old. Normally, as one ages,maximum oxygen consumption decreases.The national norm for maximum oxygenconsumption in 50-year-old individuals is 30milliliters per kilogram per minute, with astandard deviation of 8.6. The mean of the 14individuals is 40 milliliters per kilogram perminute. What can you conclude? Use alpha =.05 (one-tail).1/1ETT[T16 -
