The tension on the mesh of ne wires that lies behind the surface of the viewing screen of high resolution video terminals is measure in millivolts {my}. A manufacturer's study has shown that when the process is operating properly, the standard deviation of the tension is or = 43 m'v'. The manufacturer obtained tension readings from an SR5 of 2C! screens, and found that the sample mean is E = 306.3 mv. What is the margin of error for a 96% condence interval? 1ll'll'rite your answer with accuracy to one decimal place
