You are interested in enhancing the performance of runners in a 10-kilometer event. You randomly select 40 runners and randomly assign them to one of two diet groups. During the 24 hours prior to the 10K run you feed the experimental group a special diet of 80% of their calories from carbohydrates and ad lib water intake. During the 24 hours prior to the event you tell the control group to eat what they normally would eat and drink prior to a 10-K race. Prior to running the event you measure the glycogen content of the quadriceps muscle in mg/kilogram of wet muscle of each subject. You also measure the individual’s time to run the 10K event. Thus, the purpose of your study is to determine the effect of a high carbohydrate diet on glycogen content of the muscle and 10k performance. A secondary purpose is to examine the relationships between glycogen content of the quadriceps and 10K performance. For each statistical hypothesis set indicate the type of question (Descriptive, Relationship, Difference) and the level of measurement of the dependent variable. Based on the type of question and the level of measurement identify the appropriate parametric tes

For each parametric test assess if the assumptions of the test are met. If the assumptions are not met what is the appropriate non-parametric test?
