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 0.57 volts, and the manufacturer wishes to test Hou= 5 volts against H₁: 5 volts, using n = 8 units. In your intermediate calculations, use z-scores rounded to 2 decimal places (e.g. 98.76). Round your answers to 4 decimal places (e.g. 98.7654). (a) The acceptance region is 4.84 <<5.19. Find the value of a. Ex: 0.2222 (b) Find the power of the test for detecting a true mean output voltage of 5.1 volts. Ex: 0.2222
