5. Consider the following five observations on y= {5, 2, 3, 2, -2) and x = {3, 2, 1, -1, 03.
(a) Find 21x?, Στ-1*y., Σι*, Σξ-19, x, y.
(b) Find b, and b₂ and give an interpretation of each.
(c) On a graph, plot the data points and sketch the fitted regression line, ŷ=b₂ + b₂xt
(d) On the sketch in part (c), locate the point of means (y). Does your fitted line pass
through that point?
