### The t-test

Students will practice t-test calculations using their TI-84 technology, just as they will be required to do so during examinations.

### Testing Claims About Proportions

Students find z-scores and critical values to test claims about proportions.

### Comparing Two Means

Students test hypotheses concerning means of two populations by calculating the test statistic and the critical values and graphing the critical region.

### Goodness-Of-Fit

Students test claims of whether given distributions "fit" theoretical distributions.

### Candy Pieces

Students use a chi-square test for goodness-of-fit to determine if there is a significant difference between the proportions they find in the sample, and the proportions they would expect if the manufacturer produced equal proportions of each color.

### Claims About Two Proportions

Students test claims about two proportions by calculating test statistics, critical values, and P-values, for both one-tailed and two-tailed tests.

### Hypothesis Testing: Means

Students test a claim about a mean with a large sample size at the five-percent significance level. The test statistic is found and compared to the critical value.

### Inference for Two-way Tables

Students use the chi-square test to analyze whether two categorical variables are independent or dependent calculating expected frequencies, the test statistic and the critical values.

### What! A Mistake!

Students learn about Type I and Type II errors. Then, for a given scenario, they calculate the probabilities of errors and the power of the test.
