For your assigned scenario, state the null and alternate hypotheses (if applicable), indicate what would be the appropriate hypothesis test or analysis technique, and state why you selected that technique.

A researcher wants to determine if the reaction speeds of people are different based on whether they are athletic, moderately athletic, or not athletic. A random sample of people were asked whether they were athletic, moderately athletic, or not athletic. Then they were tested for reaction speed. Reaction speed was measured indirectly through reaction distance, as follows: A vertical meter stick was dropped and they caught it. The distance (in centimeters) that the stick fell is the reaction distance, and shorter distances correspond to faster reaction times.

Explanation / Answer

Answer: One way of the varaince or ANOVA should be used here because we want to test mean of response speeds under 3 different groups. i,e, athletic, moderately athletic or not athletic.
