- Students will discuss scenarios when best to use a t-test.

About the LessonStudents will be given several examples of data. They will do the following for each example:
- Write down the null and alternative hypotheses.
- State whether the example is a one-tailed or a two-tailed test.
- Using the handheld, students will find the t-value and p-value for a 2 sample t-test at the 5% significance level.
- Write down the conclusion to the test.
