Final answer:
The correlation coefficient is a statistical measure that quantifies the strength and direction of the linear relationship between two variables. To predict your driving test score if you spent 50 hours driving, you would need the regression equation. Whether the predicted driving test score seems reasonable depends on various factors.
Step-by-step explanation:
The correlation coefficient is a statistical measure that quantifies the strength and direction of the linear relationship between two variables. It is represented by the symbol 'r' and can range from -1 to 1. A value of 1 indicates a perfect positive correlation, a value of -1 indicates a perfect negative correlation, and a value of 0 indicates no correlation.
To predict your driving test score if you spent 50 hours driving, you would need the regression equation. If you have the equation, you can substitute the value of 50 for the independent variable (hours driving) and calculate the predicted value for the dependent variable (driving test score).
Whether the predicted driving test score seems reasonable can depend on various factors, such as the range of scores, the variability in scores, and the accuracy of the regression model. Without more information, it is difficult to determine the reasonableness of the prediction. Further analysis and evaluation of the regression model would be necessary.
