7) From a list of faculty sizes for American 4-year colleges and universities, it is desired to estimate the average faculty size for an academic year. Public schools are typically larger compared to private ones, so stratification is appropriate. The type of school (public vs private) is easily obtained, whereas faculty data are more difficult to capture. A sample of 141 schools obtained the following: Private Public Total n, 84 n=57 n'=141 Use the information given there to estimate the average faculty size for American colleges in this study. Construct an estimated variance for your estimate of the average and interpret.
