Help!

There are 2 questions for my homework that I am having issues with. Here is the first: 1. A physical education professor believes that exercise can slow the aging process. For the past 10 years, he has been conducting an exercise class for 100 individuals who are currently 50 years old. Normally as one ages, maximum oxygen consumption decreases. The national norm for maximum oxygen consumption in 50-year old individuals is 30 milliliters per kilogram per minute, with a SD of 8.6. If the researcher wants to detect an increase of maximum oxygen consumption of at least 2 milliliters per kilogram per minute, what is the power of this experiment to reject the null hypothesis. The second half is the exact same question but with "Using alpha - .05" on the end. Help with these 2 would be awesome!

Hi there. It is difficult to tutor, when we don't know what you've already done or thought about. Please share your work so far, or explain why you're stuck.

Using alpha - .05

I don't know what symbol alpha represents or why one might subtract 0.05 from it.

Do you have any formulas to share? :cool:
