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?
