Question

11) For the following scatter plot and regression line, at x = 48 the residual is ____.

Answer 1

To find the residual at x=48 in a scatter plot with a regression line, substitute x=48 into the regression line equation and calculate the corresponding y-value. Then, subtract this y-value from the actual y-value at x=48.

Step-by-step explanation:

The residual at x=48 is the difference between the actual y-value at x=48 and the predicted y-value at x=48, which can be found using the equation of the regression line. Since the regression line equation is not provided in the question, I cannot determine the specific residual at x=48 without that information. However, to calculate the residual, you would substitute x=48 into the regression line equation and find the corresponding y-value. Then, subtract this y-value from the actual y-value at x=48.
