Chapter 3 - Distributions of Random Variables Practice: 3.1 (see normalPlot), 3.3, 3.17 (use qqnormsim from lab 3), 3.21, 3.37, 3.41 Graded: 3.2 (see normalPlot), 3.4, 3.18 (use qqnormsim from lab 3), 3.22, 3.38, 3.42

3.2. What percent of a standard normal distribution N(μ = 0, sd = 1) is found in each region? Be sure to draw a graph.

normalPlot(mean = 0, sd = 1, bounds = c(-1.13, 4))

  1. Z <0.18
normalPlot(mean = 0, sd = 1, bounds = c(-4, 0.18))

  1. Z >8
normalPlot(mean = 0, sd = 1, bounds = c(8, 8))

  1. |Z|<0.5
normalPlot(mean = 0, sd = 1, bounds = c(-4, -.5))
