Test Tomorrow!

Tonight STUDY, STUDY, STUDY! End the third quarter with your highest test grade thus far!


The test has two sections:

• Vocab Section
• 20 matching terms to definitions
• 5 questions on the back where you are given a context/scenario and asked what type of test or interval would be used for that scenario!
• Here's the vocab list (chapters 19 to 22):

• Confidence Interval
• Hypothesis Test
• Critical Value
• Standard Error
• Margin of Error
• Confidence Level
• Null Hypothesis
• Alternative Hypothesis
• Standardized Test Statistic
• P-Value
• Alpha level (know 2 definitions)
• Beta
• Reject the null hypothesis (for what types of p-values?)
• Fail to reject the null hypothesis (for what types of p-values?)
• One tailed test (a test that aims to show an increase or decrease in a parameter)
• Two tailed test (a test that aims to show a difference or change in a parameter)
• Type 1 Error
• Type 2 Error
• Power
• Pooling (when we combine our sample data (from both samples) to calculate an overall proportion)

• Math Section: covering all of 2 proportion z intervals and tests! (chapter 22)
• Look over your weekend homework (key posted below)! This homework outlines everything you need to know for the test!
• You can also look over the "Types of Error" stamp and the 3 multiple choice questions that were passed back today!
• Want more math practice?! Try the "Chapter 22 Quiz B" below! (period A I forgot to hand this out, sorry about that!)

Chapter 22 Quiz B

In 2000, the United Nations claimed that there was a higher rate of illiteracy in men than in women from the country of Qatar. A humanitarian organization went to Qatar to conduct a random sample. The results showed that 45 out of 234 men and 42 out of 251 women were classified as illiterate on the same measurement test.

1. Do the samples above provide evidence that the United Nations’ claim was correct—that there was a higher illiteracy rate in men than in women (in Qatar)? Test an appropriate hypothesis and state your conclusion.
2. Show the appropriate mathematics and calculate a 95% confidence interval for the difference in proportions of illiteracy in men and women from Qatar. Then, interpret your interval.
