Final answer:

The linear regression for the data is y = -173.51 + 4.83x. The correlation coefficient is r = 0.663.

Step-by-step explanation:

To find the linear regression for the given data, we use the equation of the best-fit line: y = -173.51 + 4.83x. The slope of the line is 4.83, which represents the rate of change of the dependent variable with respect to the independent variable. The y-intercept of the line is -173.51, which represents the value of the dependent variable when the independent variable is zero.

The correlation coefficient for the data is r = 0.663. This value shows the strength and direction of the linear relationship between the x and y values. In this case, a positive value indicates a positive linear relationship, meaning that as the x values increase, the y values also increase.
