Normal Distribution Name Class Assume that X has a normal distribution. Use the calculator to find the percentages and sketch. Round to four decimal places. 1. The mean is μ = 60.0 and the standard deviation is σ = 4.0. Find the percent that X is less than 53.0. 2. The mean is μ = 15.2 and the standard deviation is σ = 0.9. Find the percent that X is greater than 15.2. 3. The mean is μ = 15.2 and the standard deviation is σ = 0.9. Find the percent that X is greater than 16.1. 4. The mean is μ = 15.2 and the standard deviation is σ = 0.9. Find the percent that X is greater than 17. © 2016 joan kessler distancemath.com Date Name 5. The mean is μ = 15.2 and the standard deviation is σ = 0.9. Find the percent that X is between 14.3 and 16.1. 6. The mean is μ = 22.0 and the standard deviation is σ = 2.4. Find the percent that X is between 19.7 and 25.3. 7. The mean is μ = 137.0 and the standard deviation is σ = 5.3. Find the percent that X is between 134.4 and 140.1. © 2016 joan kessler distancemath.com Normal Distribution Practice with the Calculator Answer Key © 2016 joan kessler distancemath.com
