Which graph is a parabola? On a coordinate plane, a curved line opens up and left in quadrants 1 and 2. It is asymptotic to the negative x axis and crosses the x-axis at (negative 4, 0) and crosses the y-axis at (0, 1). On a coordinate plane, a curved line opens up and down in quadrants 1 and 3. It crosses the x-axis at (negative 1, 0), turns to the right, crosses the y-axis at (0, 1), then turns up sharply. On a coordinate plane, a parabola opens up. It goes through (negative 2.2, 10), has a vertex of (0.25, negative 1), and goes through (2.6, 10). On a coordinate plane, a curved line opens up and left in quadrants 1 and 2. It goes through (negative 3.3, 10), crosses the y-axis at (0, 1), and is asymptotic to the positive x-axis.

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) ).
