a. Construct a scatter plot of the data. Indicate whether the plot suggests a linear or nonlinear relationship between the dependent and independent variables.
b. Determine how much influence one data point will have on your perception of the relationship between the independent and dependent variables by deleting the data point with the smallest x value. What appears to be the relationship between the dependent and independent variables?
