17. A researcher wanted to see what had a larger affect on weight loss and tested number of minutes of exercise (30 minutes vs. 60 minutes and 90 minutes) per day and number of hours of sleep (6, 7 or 8 hours) on their weight loss. The conditions had 9 participants each. Please fill in the missing values in table below. Start with the degrees of freedom values and using algebra calculate the other values for each category.
