What is the slope of this line? A line graphed on a Coordinate plane with x axis ranging from negative 6 to 4 and y axis ranging from negative 2 to 8. The line passes through the points begin ordered pair 1 comma 6 end ordered pair and begin ordered pair negative 3 comma negative 2 end ordered pair.

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) ).
