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 0.89 volt, and the manufacturer wishes to test Ho: = 5 volts against H:4 + 5 volts, using n = 5 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 4.80
