• Q1: Find the z value to the right of the mean so that (2 points each) 1. 54.78% of the area under the distribution curve lies to the left of it. 2. 69.85% of the area under the distribution curve lies to the left of it. 3. 88.10% of the area under the distribution curve lies to the left of it. Q2: An instructor gives a 100-point examination in which the grades are normally distributed, the grades are A, B, C, D, E and F. The mean is 60 and the standard deviation is 10. If there are 5% A’s and 5% F’s, 15% B’s and 15% D’s, and 60% C’s, find the scores that divide the distribution into those categories (10 points)
