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 0.25 V, and the manufacturer wished to test Hg: H = 8 against H1: u # 8, using n = 10 units. Statistical Tables and Charts (a) The critical region is < 7.86="" orī=""> 8.14. Find the value of a. Round the answer to 3 decimal places. a = 1 eTextbook and Media (b) Find the power of the test for detecting a true mean output voltage of 8.08 V. Round the answer to 3 decimal places. The power of the test is 1 eTextbook and Media
