A multivаriаte dаta set оn оffice wоrker productivity is to be collected involving a sample of 80 employees. The quantitative variables of interest are hours worked (HrsWrk), hours trained (HrsTrn), client satisfaction (ClientSat), and supervisor satisfaction (SuperSat). Let denote the variable measurement for the employee. The sample covariance matrix for these variables is observed to be (rounded): (4pts) What (if anything) can we say about the relationship between hours worked and client satisfaction? For any formulas you wish to use to support your answer, you should explain how you would use them, but you don't have to simplify them numerically. (2pts) Suppose instead of the above covariance matrix, we work from the conditional covariance matrix of hours worked and client satisfaction, given hours trained. How does this change the interpretation, compared with the one above? Which would you prefer and why?
