- Test includes...
- Matching Vocab
- AP FR
- AP MC
- The AP MC and FR will definitely have some "2 prop z" stuff, but can also include any topics from our last test!
- Here's the vocab list for tomorrow (chapters 19, 20, and 21)
- We did not have a chapter 21 vocab quiz, so some of these terms have not been on passed quizzes
- Confidence Interval
- Hypothesis Test
- Sample Statistic v. Population Parameter (given a value determine if it's a statistic or parameter; be sure you also know the symbols for each statistic or parameter)
- Sampling Variability
- Margin of Error
- Critical Value
- Standard error
- Interpret C. Level v. Interpret C. Interval
- Point Estimate
- Know how changing our confidence level and/or our sample size affects the ME and the width of an interval
- Null Hypothesis
- Alternative Hypothesis
- One v. Two Tailed Test
- Alpha Level/Significance Level
- Reject Ho (when do we reject? there is or is not evidence?)
- Fail to Reject Ho (when do we fail to reject? there is or is not evidence?)
- P-Value
- Standardized Test Statistic
- Type I Error
- Type II Error
- Alpha (in relation to types of error)
- Beta (in relation to types of error)
- Know how alpha and beta relate
- How can we decrease both alpha and beta?
- Power
- Know when to use a 1 prop z test, 1 prop z interval, 2 prop z test, or 2 prop z interval
- There will be another matching section where you have to match the correct procedure to a given context
- Other stuff to know....I'm typing this as I look at the (not vocab section of the) test....
- How to do a full 2 proportion z interval (conditions, math, interpret)
- How can we use a 2 prop z interval to determine if there is a significant difference in two proportions?
- How to conduct a full 2 proportion z test (hypotheses, conditions, math, interpret)
- Describe a Type 1 and Type II error (for 2 prop z contexts)
- Calculate margin of error (for 1 or 2 prop z)
- How to find sample size (back to 1 prop z stuff)
- Be sure you know how to find p-hat and the margin of error given only a confidence interval
- Study the weekend homework! Key in the post below!
- And be sure to look over the 3 multiple choice (stamps) I passed back today!
In period D we discussed the calculation of the standardized test statistics (z or t score)--check out these notes!
