A manufacturer 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 0.75 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 ≤ 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.
