Any remaining questions from Chapter 15 or the activity for discrete RVs?

Chapter 17 - Continuous Random Variables

• Normal Distribution - pnorm, qnorm, and rnorm in R
  • some students prefer xpnorm and xqnorm with the mosaic package
  • See NormalDist.R for some examples
• Examples and assessing normality - See NormalQuantilePlots.Rmd

Activity

• Create an R script or Markdown file to simulate 100 observations from a normal distribution with different means and standard deviations. After simulating the random observations, construct a normal quantile plot to assess normality. Can you estimate the mean and standard deviation of a normal distribution from the normal quantile plot? If so, explain how. If not, explain why not.

Please read Chapter 4 I/O: Input and Output and Chapter 17 Continuous Random Variables for class on Wednesday
