Given the linear regression model: Yi = Bo+B1x1 + ẞ2xi2 + Єi, i = 1,..., n Consider the following sums from n = 10 observations on Y, X1, and X2: 10 10 10 Σ3 = 20, Σ i=1 10 Συ? = 98.2, i=1 i=1 10 10 10 71 =0.0, Σ i=1 10 x12 = 0.0 Σαμ = 92, Σα? i=1 = 163 i=1 10 Σ Yixil = 59, Yixi2 = 88, Xi1i2=119 i=1 i=1 i=1 Explore the following steps: 1. Construct the XTX matrix and the vector XTy. 2. Calculate the least-squares estimates of Bo, B1, and ẞ2, along with the residual sum of squares, SSE. 3. Investigate the hypothesis that the coefficient of X 2, represented by 32, is zero.
