Data Graphs Our first quantitative variable is cell phone minutes used in a month. The unit of measurement for this variable is minutes. A few possible values for this first quantitative variable are 300, 500 and 700. Our second quantitative variable is age. The unit of measurement for this variable is whole integers. A few possible values for this second quantitative variable are 15, 25, 35, 45.

Conclusion The t-table shows that the critical value is roughly 0.195
Linear Correlation Coefficient: r= Equation for line of regression: -2.19x Correlation coefficient: The correlation coefficient suggests that there is a small relationship between both variables, Age and Cell Minutes used. The data shows that age plays a small role in the number of minutes used, which is the older ones age is, the fewer cell minutes used.
