Lesson 12 Larger Populatoins

• For each sample given, list two possible populations they could belong to.

1. Sample: The prices for apples at two stores near your house.

• For each sample given, list two possible populations they could belong to.

1. Sample: The days of the week the students in your math class ordered food during the past week.

• For each sample given, list two possible populations they could belong to.

1. Sample: The daily high temperatures for the capital cities of all 50 U.S. states over the past year.

1. Based on this data, do you think that sales were generally higher in the spring than in the fall?

1. The MAD for the fall data is 2.8 cookies. The MAD for the spring data is 2.6 cookies.

2. Express the difference in means as a multiple of the larger MAD.

(Subtract the Spring mean from the fall mean, then divide by the fall mean)
