question 60

Multiple Choice

It is determined that a positive linear association exists between amount of a new smoking cessation drug taken (in milliliters) and weight gain in women (in pounds) . The scatterplot below shows the association. The prediction equation is also given. A pharmacy technician uses the model to predict the potential weight gain for a man who takes the recommended dosage. Choose the best statement to summarize why this is not an appropriate use for the model.

• A)This is an inappropriate use of the model because taking the smoking cessation drug does not cause weight gain. Correlation does not mean causation.
• B)This is an inappropriate use of the model because a man would be an outlier in this context.
• C)This is an inappropriate use of the model because the model was used to make predictions beyond the scope of the data. The Pharmecy Technician is extrapolating.
