For a hypothesis test of the claim that the mean amount of sleep for adults is less than 9 hours, technology output shows that the hypothesis test has power of 0.4816 of supporting the claim that μ<9 hours of sleep when the actual population mean is 7.5 hours of sleep. Interpret this value of the power, then identify the value of β and interpret that value. Interpret this value of the power. A. The chance of recognizing that μ<9 hours is not very high when in reality μ=7.5 hours. B. The chance of failing to recognize that μ=7.5 hours is not very high when in reality μ=7.5 hours. C. The chance of recognizing that μ<9 hours is very high when in reality μ=7.5 hours. D. The chance of failing to recognize that μ<9 hours is not very high when in reality μ=7.5 hours.
