Dear forum pal,
Here is my problem:
- We would like to buid an experiment in order to check the effect of a new energy drink that is destined to the olympic sprinters (100m).
- Here are our requirements for the experiment.
- Type I error = alpha = less than 0.05
- Power = 1-beta = better than 0.80
If the results difference over 100 meter between someone who used the drink and someone who did not is 0.1%, what is the required sampling size ?
Same question for a difference of 0.2 %, 2.5%, 3.6%, 4.0% and 4.7%
Please try to help us.
If our question lacks any other information please let us know.
