A continuous random variable, X, is found to be uniformly distributed over the interval 4≤x≤9. What is the probability that a number randomly chosen from this interval is in the interval 3≤x≤8? Give the notation of the distribution and the notation of the probability that would be calculated.

A total of 130 people had their body temperature tested. The subjects were grouped based on if they were men (M) or women (W) and if they had a high (H) or low (L) pulse rate. This gives four groups of people: MH, ML, WH, WL. What distribution (and degrees of freedom) would be used to test if mean body temperatures for these four groups are equal?
