Suppose the statistics department at a large midwestern university has offered the same course in biostatistics for many semesters. Let U be a discrete random variable with values equal to the number of undergraduate students who register each semester. The mean of U is uu = 160 undergraduate students and the standard deviation is ou = 16 undergraduate !! students. Let G be a discrete random variable with values cqual to the number of graduate students who register each semester. The mean of G is UG 40 graduate students and the standard deviation is oG 12 graduate students. %3D Compute the mean, HU+G- of the total number of undergraduate and graduate students registered.

Question
Suppose the statistics department at a large midwestern university has offered the same course in biostatistics for many semesters. Let U be a discrete random variable with values cqual to the number of undergraduate students who register each semester. The mean of U is pu = 160 undergraduate students and the standard deviation is oU = 16 undergraduate students. Let G be a discrete random variable with values cqual to the number of graduate students who register each semester. The mean of G is µG = 40 graduate students and the standard deviation is og = 12 graduate students. Compute the mean, HU+G, of the total number of undergraduate and graduate students registered. Give your answer as a whole number. students HU+G Compute the standard deviation, ou+G, of the total number of undergraduate and graduate students registered. Assume the variables U and G are uncorrelated, and report your answer as a whole number. students OU+G = 27%
