Problem 5 (35 points) Let (x1,y1),(x2,y2),(x3,y3),,(x7,y7) be a simple random sample from a population of bivariate data. The variable X is x1,x2,x3,,x7. The variable Y is y1,y2,y3,, y7. The values of the terms in the sample are presented in the table below. (A) Hand draw the scatter plot of the sample. (B) Most likely, which data point is an outlier? (C) If we are sure that the outlier is due to a data-recording error, calculate the leastsquares coefficients for the least-squares line for the sample. Then, write down the equation for the least-squares line. (D) If the source of the outlier is unknown, calculate the least-squares coefficients for the least-squares line for the sample. Then, write down the equation for the leastsquares line
