The Dean at University of Maryland is concerned about the high cost of textbooks for each semester. A sample of 75 students enrolled indicates that X(bar) = $285.40 and s = $42.20. Using a 0.05 level of significance, is there evidence that the population mean is above $300.00?1 AnswerOther - Business & Finance9 years ago
