Charlotte is writing statements to prove that the sum of the measures of interior angles of triangle pqr is equal to 180o. line m is parallel to line n.. line n is parallel to line m. triangle pqr has vertex p on line n and vertices q and r on line m. angle qpr is 70 degrees. segment pq makes 35 degree angle with line n and segment pr makes 75 degree angle with line n.. which is a true statement she could write? . answer. angle prq measures 35o.. angle pqr measures 70o.. angle prq measures 70o.. angle prq measures 75o.

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) ).
