Chapter 1: Q.66 (page 54)

Suppose you want to determine the mean number of students per statistics class in your state. Describe a possible sampling method in three to five complete sentences. Make the description detailed.

Short Answer

Expert verified

Stratified sampling should be used to determine the number of students per statistics class in a state. To do so, divide the state into some strata (create strata according to area), then select some statistics classes from the modified strata, and conduct analysis to determine the number of students per statistics class. The acquired value is then used to predict the number of students in each statistics class in that state.

Step by step solution

To determine

The method for determining the average number of students in each statistics class in your state.

Explanation

Within the state, there would be a number of Statistics classes. The first step would be to divide the state into distinct geographical areas. Because certain places may offer more classes than others, it's critical to choose the quantity of classes proportionately from each area. Once the classes in the sample have been chosen, the number of students in each class is recorded, and the average of all the selected classes is calculated to arrive at the state's mean number of students in Statistics class.
