Amanufacturer 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 0.87 volt, and the manufacturer wishes to test upper h subscript 0 baseline colon mu equals 5 volts against upper h subscript 1 baseline colon mu not-equals 5 volts, using units. round your answers to four decimal places (e. g. 98.7654). (a) the acceptance region is 4.87 less-than-or-equal-to x overscript bar endscripts less-than-or-equal-to 5.20. find the value of alpha. (b) find the power of the test for detecting a true mean output voltage of 5.1 volts.\c
