The Normal distribution curve to the right displays the distribution of grades given to managers based on management performance at Ford. Of the large population of Ford managers, 10% were given A grades, 80% were given B grades, and 10% were given C grades. A’s were given to those who scored 380 or higher and C’s were given to those who scored 160 or lower. Suppose the company adds grades D and F so there are 5 categories to grade performance. If they want to give A’s only to those in the top 3%, what performance score must a manager exceed to get an A?
