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 0.25 V, and the manufacturer wished to test against 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.
