Normal Distribution (continued) Ex 1: If 𝑋~𝑁(50, 52 ), draw a diagram that represents the percent of data that have these values for X: a) 𝑥 > 55 b) 40 < 𝑥 < 60 c) 𝑥 < 38 Ex 2: To run without causing damage, diameters of engine crankshafts for a certain car model must fall between 223.91 mm and 224.09 mm. Crankshaft diameters are normally distributed, with a mean of 224 mm and a standard deviation of 0.03 mm. What percent of these crankshafts are likely to cause damage? Homework: Pg. 178: #12, 13-18
