Chi-square Tests

 Data Collection and Analysis

This activity comes from the DeVeaux and Velleman book. Ask your class (this is the data collection part) to select one of the numbers 1, 2, 3 or 4. Write them on the board and ask the class to select at random. The claim is that most collections of people will select these in these proportions: 5%, 10%, 75%, 10%.

Here's the analysis part: is your class in agreement with the DeVeaux/Velleman claim?

Post your data and conclusion on the Discussion Board, if your instructor is using a discussion forum.
