Question: A survey was conducted at a large metropolitan university campus. Twenty-four students were interviewed. Two of the questions asked were: "How many hours per week are you employed?" and "How many credit hours are you currently registered for?"

1. Use MINITAB to make a scatterplot for the above data. (Turn in a paper copy.) Put \(y\) on the vertical axis.
2. Is there a strong correlation between \(\mathrm{x}\) and y?
3. Use the regression line to predict the number of credit hours for a student employed 18 hours a week. Comment on how accurate this prediction might be.
4. Repeat parts a, b, and c for those students who are employed (i.e. exclude people who do not work). Which of the two approaches is better for the 18 hour prediction?
