Q1 Let X be the number of minutes that it takes a random selected student to solve a mathematical problem. The probability density function of X is: S(2) = 27 (6 + z -2²), 0sz53 otherwise (a) Find the probability that a student takes less than 1.5 minutes to solve the mathematical problem. (b) If we change question Q1(a) to P (0 < X S 1.5), will we get the same answer? Give your justification. (c) Find the mean of X. (d) Find the standard deviation of X.
