Candy Pieces

Published on

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.

Hypothesis Testing: Means

Published on

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.

What! A Mistake!

Published on

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.
