Question:
Refer to Exercise 12.
A test of the hypotheses H0: ???? = 10 versus H1: μ ≠ 10 will be made at the α = 0.05 level of significance. Assume that the standard deviation of moisture content is σ = 5.0 and that the sample size is n = 50.
Find the power of the test against the alternative
μ1 = 12.
Exercise 12 Shipments of coffee beans are checked for moisture content. A high moisture content indicates water contamination and will result in the shipment being rejected.
Let μ represent the mean water content (in percent by weight)
in a shipment. Fifty moisture measurements will be made on beans chosen at random from the shipment. A test of the hypotheses H0: μ = 10 versus H1: μ > 10 will be made at the
???? = 0.05 level of significance. Assume the standard deviation of moisture content is σ = 5.0.
