2. (8 marks) Four groups of participants were randomly selected from KINE 1000. One group was fed a balanced diet containing fats (F), proteins (P), and carbohydrates (C) called the FPC group. The diets of the other groups were identical except that one of the three nutrients was absent, with a different deficiency for each group. After three days under these conditions, all subjects were required to run an obstacle course as a test of their physical fitness. The number of minutes each subject required to complete the course was recorded.

Fully labelled, with error bars and figure caption (2 marks). d) Using Excel and/or other statistical tests, run a one-way ANOVA, and any required follow-up tests. Show output (2 marks) e) Interpret your results using a report similar to those described in class and shown for previous labs.
