Length (mm) Weight (mg) Insect 1 6 19 Insect 2 14 31 Insect 3 25 48 Insect 4 17 37 Insect 5 8 20 Insect 6 22 51 Insect 7 4 11 Derrick used the data to compute the least squares regression line: Q = 1.848x + 5.658 where length is the explanatory variable and weight is the response variable. (a) Plot the data in a scatterplot and label the graph appropriately. Draw the leastsquares regression line on the graph to the best of your ability. (b) Calculate the residual values for each of Derrick's data points. Round to three decimal places. (c) Create the residual plot for this data and include the horizontal line at 0. Describe the pattern of the residuals. Be sure to label the plot appropri ately
