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 volts, 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.

The answer is 7.2 how would you put this as money
