Review:

  • Probability

Presentation:

  • Sampling Distributions
    • Take multiple Simple Random Samples, sample size = n, and calculate sample mean
    • “Sampling Distribution” is the distribution of sample means
    • Standard deviation of sample means = σ/√n
    • Example 5.18 on p. 338
  • Central Limit Theorem
    • Simple random samples of size n from any population with mean μ and finite standard distribution σ. When n is large (typically ≥ 30), the sampling distribution of the sample mean is approximately Normal.
    • Example 5.19 on p. 339
  • Video

Activity:

  • Complete Exercises 5.36, 5.37, 5.38, 5.39 on pp. 336-340

Assignment:

  • Read pp. 335-344, Sampling Distribution of a Sample Mean
