1. In her class in Accounting, Miss Kay told the students that they need a grade in the top 10% of the class to get an A in a particular test. In the standardization of the test, the mean was 70 and the standard deviation was 12. Assuming that the grades would be nomally distributed, what must be the minimum grade needed to oblain an A? a) Does the normal curve apply in the problem? b) Under the curve, where is the top 10% located? c) In the Final run, what do we need to find ----a z or a raw Scoret
