Since the individual stress scores follow a uniform distribution, X ~ U(1, 5) where a = 1 and b = 5 (See Continuous Random Variables for an explanation on the uniform distribution). If the population is normally distributed, then the. Problems c and d ask you to find a probability or a percentile for a total or sum. The Central Limit Theorem (CLT) describes the shape of the sampling distribution of the sample mean. Problems a and b ask you to find a probability or a percentile for a mean. The 90 th percentile for the total stress score for the 75 students.The probability that the total of the 75 stress scores is less than 200.The 90 th percentile for the mean stress score for the 75 students.The probability that the mean stress score for the 75 students is less than two.The stress scores follow a uniform distribution with the lowest stress score equal to one and the highest equal to five. A study involving stress is conducted among the students on a college campus.
