Least Square Line Equation = Let (Ji, yi), i = 1, 2, ..., 10 represent the earning of 10 businesses, measured in $1000, in a city for two consecutive months; x representing the March earnings and y representing the April earnings. The following table summarizes the data. Summary of 10 Business Earnings [in $1000] for March and April Months March (X) April (Y) Sample Size 10 10 Mean 7.89 6.53 Variance 0.432 1.313 The covariance of X and Y is 0.4959. Recall: X = 121-14, Var[X] = D= (; – )2, and Cov[X,Y] = in 1 (xi – 7)(yi - y). Use the given information to answer the following questions. You may need the following equations to answer those questions: SST = (:- )2 SD[X] = $x = Var[X], and Cov[X,Y) Cor[X, Y] =r= SX SY
