Question

Suppose you want to determine the mean number of cans of soda drunk each month by students in their twenties at your school. Describe a possible sampling method in three to five complete sentences. Make the description detailed.

Answer 1

One possible sampling method is stratified sampling, where the population is divided into different groups or strata based on certain characteristics. Randomly selecting a certain number of classes from each stratum would provide a representative sample for determining the mean number of students per statistics class in the state.

Step-by-step explanation:

A possible sampling method to determine the mean number of students per statistics class in your state is stratified sampling. Stratified sampling involves dividing the population into different groups or strata based on certain characteristics. In this case, you could divide the population into different statistics classes and then randomly select a certain number of classes from each stratum. This ensures representation from different classes and reduces the risk of bias in the sample.

For example, if there are 100 statistics classes in the state, you could randomly select 10 classes from each of the 10 strata (dividing the classes into 10 strata based on some characteristic such as class size or location). This would result in a sample of 100 classes.

This method allows you to collect data that is representative of the population and provides a more accurate estimate of the mean number of students per statistics class in the state.

Answer 2

The possible sampling method that can be used to determine the mean number of soda drunk by students is systematic sampling. this simply means adopting a system of interviewing the students in order to get the average value of the number of students who drink soda and this can be done by interviewing every 2nd student entering the school cafeteria every day

Step-by-step explanation:

The mean number also known as the average number of a series of events can be gotten by summing up the numbers and dividing the sum by the frequency of each event
