In an experiment to compare the tensile strengths of I = 6 different types of copper wire, J = 5 samples of each type were used. The average between group and average within group estimates were computed as MSTr = 2616.3 and MSE = 1106.2, respectively. Often hypothesis tests are conducted using what is referred to as the rejection region method. This compares the calculated F test statistic to an F value that cuts off a "rejection region". If the calculated test statistic falls within the rejection region, the null is rejected. The F value that represents the cut off for the rejection region, is the F value that cuts off the top α% of area in an F distribution with I-1 and I(J-1) degrees of freedom. In other words, if α = 0.05, the F rejection region cut off will be the 95th percentile from the appropriate F distribution.

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.

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) ).
