Extracted text: 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 0.48 volt, and the manufacturer wishes to test Ho : µ = 5 volts against Hị : µ # 5 volts, using n = 9 units. In your intermediate calculations, use z-scores rounded to two decimal places (e.g. 98.76). Round your answers to four decimal places (e.g. 98.7654). (a) The acceptance region is 4.86
