Regression The data below are claimed to relate to four experiments, which were conducted with the objective of investigating the effect of the value of a variable x on the associated value of a variable y. In each experiment the same values of x were used: thus only one column of x- values is given, while there are four columns of y-values, one for each experiment. X у1 Y2 Y3 y4 10-0 21-26 22.40 20-70 22.94 8.0 20-57 21-84 20-43 19-85 13.0 20-15 21-35 25-31 19-65 9.0 22-28 22.15 20-56 20-25 11.0 21-36 22-27 20-80 22.38 14-0 22.30 20-43 21-19 23-84 6.0 21-35 20-25 20-21 20-55 4-0 18-81 17.66 19.90 19.53 12-0 7-0 5.0 23-63 21-90 20-95 21-55 18-73 21.15 20-31 19-72 20-01 19.05 20-09 20-19 ... For each set of data: (i) obtain the equation of the least squares regression line of y on x; (ii) plot the data, and comment on the results.
