Introduction
Have you checked the content labels of the things you bought lately?

Do you really believe that a 12 oz. coke does actually contain 12 oz.?

Hmmmmm, why not check things out?

Methods of statistics are truly fascinating when they are used to show that a common “belief” is incorrect (Triola, 1995).

This activity will help you learn some statistical methods on how to check if content labels of goods are consistent with their actual content. You will also know what and how statistical hypothesis are formulated and stated. You will also have the opportunity of knowing some statistical tests to be used in hypothesis testing.

Let us get you started by choosing a partner. Make sure that you or your partner has a computer at home and is internet connected so that you can do this at home. Please answer the questions below by referring to the suggested websites. A website may contain answers to several questions.

Make your quest enjoyable by putting in your mind that you are doing this activity for everybody’s favor. That is, you are being trained to check if these companies whom we have learned to trust are being honest to us.

Good luck detectives………

Hypothesize that the mean content is the amount that is in its label.

Submit your results in a short bond paper (8.5 x 11), showing the steps in hypothesis testing and state your conclusions.
