Question

the data in the table to the right are based on the results of a survey comparing the commute time of adults to their score on a well - being test. complete parts (a) through (d). click the icon to view the table of critical values of the correlation coefficient. (a) which variable is likely the explanatory variable and which is the response variable? a. the explanatory variable is commute time and the response variable is the well - being score because commute time affects the well - being score. b. the explanatory variable is the well - being score and the response variable is commute time because commute time affects the well - being score. c. the explanatory variable is commute time and the response variable is the well - being score because well - being score affects the commute time score. d. the explanatory variable is the well - being score and the response variable is commute time because well - being score affects the commute time.

Explanation:

An explanatory variable is the independent variable, which is thought to influence the dependent variable (response variable). Here, commute time is likely to affect the well - being score. For example, longer commutes might cause more stress, reducing the well - being score.

Answer:

A. The explanatory variable is commute time and the response variable is the well - being score because commute time affects the well - being score.
