Refer to the previous exercise. Suppose a student's Calculus I grade is determined by $4 X+Y$ , the total score across five tests. (a) Find the mean and standard deviation of $4 X+Y .$ (b) Determine $P(4 X+Y<320)$ (c) Suppose the instructor sets the curve in such a way that the top 15$\%$ of students, based on total score across the five tests, will receive As. What point total is required to get an $\mathrm{A}$ in Calculus I?
