Question:

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 Volts, and the manufacturer wishes to test H0: μ  5 Volts against H1: Volts, using n 8 units.
(a) The acceptance region is Find the value of a.
(b) Find the power of the test for detecting a true mean output voltage of 5.1 Volts.
