Question
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 <i < 5.18. Find the value of a.
(b) Find the power of the test for detecting a true mean output voltage of 5.1 volts.
(a)
(b)
