NOTE: DONOT SOLVE ON EXCEL

a) Find the mean and standard deviation of the random variable whose probability density function is given by f(x) where: s2(1- x) 0<x<1 f(x) = {?(",*) elsewhere b) Most graduate schools of Management Science require applicants for admission to take an entry examination. Scores on one such entry exams are normally distributed with a mean of 527 and a standard deviation of 112. What is the probability of an individual scoring between 250 and 500 in this entry exam?
