Graph parallelogram WXYZ with coordinates W(-9,9) X(-6,9) Y(-4,4) Z(-11,4).Translate by moving right 5 and up 2. What are the coordinates of the transformed image? Line segment WX and line segment YZ are parallel. In the transformed image, is line segment W’Z’ parallel to line segment Y’Z’? Explain your answer.

Consider the linear model for a two-stage nested design with b nested in a as given below. yijk=\small \mu + \small \taui + \small \betaj(i) + \small \varepsilon(ij)k , for i=1,; j= ; k=1, assumption: \small \varepsilon(ij)k ~ iid n (0, \small \sigma2) ; \small \taui ~ iid n(0, \small \sigmat2 ); \tiny \sum_{j=1}^{b} \small \betaj(i) =0; \small \varepsilon(ij)k and \small \taui are independent. using only the given information, derive the least square estimator of \small \betaj(i) using the appropriate constraints (sum to zero constraints) and derive e(msb(a) ).
