In an effort to inform political leaders and economists discussing the deregulation of electric and gas utilities, data on eight numerical variables from utility companies have been grouped using hierarchical clustering based on Euclidean distance as the similarity measure and complete linkage as the clustering method. (a) Based on the following dendrogram, what is the most appropriate number of clusters to organize these utility companies? clusters are appropriate based on complete linkage. (b) Using the following data on the Observations 10, 13, 4, and 20, confirm that the complete linkage distance between the cluster containing {10, 13} and the cluster containing {4, 20} is 2.577 units as displayed in the dendrogram. If required, round your answers to three decimal places. Do not round intermediate calculations. Distance from Observation 10 and Observation 4: Distance from Observation 10 and Observation 20: Distance from Observation 13 and Observation 4: Distance from Observation 13 and Observation 20:

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) ).
