Quizplus · Accepted Answer

The data shown in the table show that the percentage of adults 20-24 years of age that have not been married decreased over the years. As time passed, more people got married, which caused the percentage of unmarried people to go down. Therefore, the linear model for this data should be a negative linear model with a negative slope.

When we look at the choices, model C is the only one that has a negative slope. Therefore, it is the best choice for this data.
