USE THE Z SCORE TABLE
To calculate the area under a normal curve, we use a the Z SCORE TABLE
1. Z = - 0.85 is 0.1977 or 19.77% (Since the sign is negative, the area willl be to the left of the mean
2. Z = 1.29 is 0.9015 or 90.15% (since the sign is positive, the area will be to the right of the mean.
