The following table shows the weight of a person and the number of hour of exercise they do. Weight 250 180 160 140 135 Hour 0 7 5 8 9 Construct a table with these headings: x-xbar, y-ybar, (x-xbar)2, (y-ybar)2, (x-xbar)(y-ybar), y-^y, and (y-^y)2. Note: ^ symbol is on top of y.  xbar is the mean for weight. ybar is the numbers of hours. ^y=a+bx where ^y is the best line of fit.  Find: a) xbar b) ^y c) b in the equation ^y=a+bx d) a '' '' '' (for each) e) r (the correlation coefficient)
