Problem 1810

For a hypothesis test of the claim that the mean amount of sleep for adults is less than 6 hours, technology output shows that the hypothesis test has power of 0.4945 of supporting the claim that μ<6\mu<6 hours of sleep when the actual population mean is 4.0 hours of sleep. Interpret this value of the power, then identify the value of β\beta and interpret that value.
Interpret this value of the power. A. The chance of failing to recognize that μ=4.0\mu=4.0 hours is not very high when in reality μ=4.0\mu=4.0 hours. B.
