Aclassmate is trying to estimate 42% of $122. explain how your classmate should solve the problem.

Grant simplified the expression 1.5(-3.2 + 2.5) his work is shown below explain the error in grants work

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) ).

Which is true about the solution to the system of inequalities shown? y > 3x + 1 y < 3x – 3 only values that satisfy y > 3x + 1 are solutions. only values that satisfy y < 3x – 3 are solutions. values that satisfy either y > 3x + 1 or y < 3x – 3 are solutions. there are no solutions.
