The test grades in some class follow a normal distribution (we will call it X) with σ = 8. Use this information (and the chart!) to answer the following questions: (a) If there is a 60% chance that a student scores higher than a 75, find µ, the average test grade for this class. (b) Using the µ you found in part (a), determine P(72 ≤ X ≤ 90).
