Using CLT sampling distribution of sample means: Large sample
- a. Z-score transformation: $Z = (x -\bar{x})/(s/\sqrt{n})$
- b. Finding probability
- c. Finding percentiles
- d. Tip: draw a density curve of the sampling distribution (x̄) and a density curve of standard normal density curve (Z)
CLT for Population Proportion
- a. Z-score transformation: $Z = (p - \hat{p})/\sqrt{p(1-p)/n}$
- b. Finding probabilities
- c. Finding percentiles
- d. Tip: draw a density curve of the sampling distribution (p̂) and a density curve of standard normal density curve (Z)
