A hypothesis test needs to be run for a population proportion. The sample taken for the test has more than five successes and more than five failures. What distribution is used for the test and what variable is used to write the hypotheses? (Choose one distribution and one variable.)

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.
