Area = 1.00
Normal (density) curves µ = 0 σ = 1 Standard normal curve Area to right of mean? 50% Half of 1.00 = 0.50 Area = 1.00 Normal (density) curves µ = 0 = 1 Standard normal curve Area to left of mean? Area = 1.00 Normal (density) curves µ = 0 = 1 Standard normal curve Area to left of mean? 50% Half of 1.00 = 0.50 Area = 1.00 Aside: Proportion vs. Percentage Proportion = Percentage / 100 Percentage = Proportion x 100
