1. Out-of-class activity Collect sample data, and use the methods of this chapter to construct confidence interval estimates of population parameters. Here are some suggestions for parameters:

● Proportion of students at your college who can raise one eyebrow without raising the other eyebrow. [These sample results are easy to obtain because survey subjects tend to raise one eyebrow (if they can) when they are approached by someone asking questions.]

● Mean age of cars driven by statistics students and or the mean age of cars driven by faculty.

● Mean length of words in New York Times editorials and mean length of words in editorials found in your local newspaper.

● Mean lengths of words in Time magazine, Newsweek magazine, and People magazine.

● Proportion of students at your college who can correctly identify the president, vice president, and secretary of state.

● Proportion of students at your college who are over the age of 18 and are registered to vote.

● Mean age of full-time students at your college.

● Proportion of motor vehicles in your region that are cars.
