Page 429: 23, 25, 27, 35
In addition, study for your chapter 18 vocab quiz tomorrow! Here's some stuff that's on the quiz (other than the vocab list at the back of chapter 18):
- Know the symbols for sample mean/proportion/standard deviation vs. population mean/proportion/standard deviation
- Make sure you know which sampling distribution is used for which type of data (categorical or quantitative)
- I might give you a few questions and ask you which requires a sampling distribution (like the slides today); remember, a sampling distribution question asks about the mean/percent of a sample
- Know what happens to standard deviation (spread) as sample size increases
- Know which conditions apply to which sampling distributions
- Vocab:
- Sampling Distribution
- Sampling Distribution for a Proportion
- Sampling Distribution for a Mean
- Standard Error
- Central Limit Theorem
- Sampling Variability/Sampling Error
- 10% Condition
- Random Sample Condition
- Success/Failure Condition
- Large Enough Sample Condition
