A multivariate data set on office worker productivity is to be collected involving a random sample of 40 employees. The quantitative variables of interest are hours trained (HrsTrn), client satisfaction (ClientSat), and supervisor satisfaction (SuperSat). Let  denote the variable measurement for the employee. (3pts) Using notation consistent with this course, what would the dimension of the data matrix be for this situation? That is, how many rows and how many columns would there be? Also, what would the dimensions of the sample mean vector and the sample covariance matrix be for this situation? (3pts) Would you expect the covariance between and to be zero or not? What about the covariance between and ? Explain your answers in the context of this situation.
