Preparing to Conduct Inference for Two-Way Tables — Quiz

Question 4 • Statistics

The organizer for the concert would like to know if these data provide convincing evidence of a relationship between age and whether they are going to tonight’s concert in the population of all people from the city. What is the appropriate inference procedure?

Answer
A
chi-square test for goodness of fit because the data come from one random sample
B
chi-square test for association/independence because the data come from one random sample
C
chi-square test for association/independence because the data come from independent random samples
D
chi-square test for homogeneity because the data come from independent random samples

Explanation

Use a chi-square test for association/independence when one random sample contains two categorical variables and the question asks whether they are related. Here, the variables are age and whether someone is going to the concert, measured for people from the city. Thus the appropriate procedure is a chi-square test for association/independence using one random sample; choice B is correct.
