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 0.14 volt, and the manufacturer wishes to test Ho: μ = 5 volts against H₁ : μ ‡ 5 volts, using n = 7 units. In your intermediate calculations, use z-scores rounded to two decimal places (e.g. 98.76). Round your answers to four decimal place (e.g. 98.7654). (a) The acceptance region is 4.85 ≤ x ≤ 5.12. Find the value of a. (b) Find the power of the test for detecting a true mean output voltage of 5.1 volts. (a) i (b) i
