The increasing annual cost (including tuition, room, board, books, and fees) to attend college has been widely discussed (Time.com). The following random samples show the annual cost of attending private and public colleges. Data are in thousands of dollars. Private Colleges Public Colleges 53.8 44.2 44.0 33.3 45.0 20.3 22.0 28.2 15.6 24.1 28.5 31.6 44.8 38.8 50.5 43.0 22.8 25.8 18.5 25.6 14.4 21.8 (a) Compute the sample mean (in thousand dollars) and sample standard deviation (in thousand dollars) for private colleges. (Round the standard deviation to two decimal places.) sample mean 42.9 thousand sample standard deviation $ 6.87 thousand Compute the sample mean (in thousand dollars) and sample standard deviation (in thousand dollars) for public colleges.
