The average undergraduate cost of tuition, fees, room, and board for all institutions last year was $ 26,025. A random sample of 40 institutions of higher learning this year indicated that the mean tuition, fees, room and board for sample was $ 27,690, and the population standard deviation is $5492. At the 0.05 level of significance, is there sufficient evidence that the cost has increased?
