Amanufacturer is interested in the output voltage of a power supply used in a pc. output voltage is assumed to be normally distributed with standard deviation 0.25 volt, and the manufacturer wishes to test h0: μ = 5 volts against h1: μ ≠ 5 volts, using n = 8 units.
(a) the acceptance region is 4.85 ≤ x-bar ≤ 5.15. find the value of α.
(b) find the power of the test for detecting a true mean output voltage of 5.1 volts.
