Final answer:
To model the data using a linear function, use a graphing calculator. The correlation coefficient of the data is 0.64.
Step-by-step explanation:
To model the data using a linear function, we can use a graphing calculator to find the equation of the least-squares regression line. The correlation coefficient, also known as r, represents the strength and direction of the linear relationship between the two variables. To find the correlation coefficient, we need to use the data points and the regression line equation. Based on the given options, the correct answer is B) 0.64.
