Final answer:To draw a scatter plot, use the home value as the independent variable and the expenditures on landscaping as the dependent variable. From the scatter plot, it can be observed that a linear relationship exists between the home value and the expenditures on landscaping. To calculate the least squares line, find the equation of the line that best fits the data points.Explanation:To draw a scatter plot, use the home value as the independent variable and the expenditures on landscaping as the dependent variable. Plot the data points on a graph, with the home value on the x-axis and the expenditures on the y-axis. Connect the points to create a scatter plot.From the scatter plot developed in part (a), it can be observed that a linear relationship exists between the home value and the expenditures on landscaping. As the home value increases, the expenditures on landscaping also tend to increase.To calculate the least squares line, find the equation of the line that best fits the data points. This equation can be written in the form ŷ = a + bx, where ŷ represents the estimated expenditures on landscaping, x represents the home value, a represents the y-intercept, and b represents the slope of the line. Use this equation to estimate the landscaping expenditures for a given home value....
