Practice making inferences from random samples.
Texas Instruments
Texas Instruments: Inferences of the Least Squares Regression
This set contains questions regarding inference for the slope of the least-squares linear regression line. The student learns to develop hypotheses, find the test statistic, and reach a conclusion in the context of the original problem.

Texas Instruments: Type I and Type Ii Errors
This set contains questions regarding Type I and Type II errors, and the power of an inference test. Students differentiate between Type I and Type II errors, and their relationship to the null and alternative hypotheses.
