A random sample of 100 items from this population is selected. The sample mean is determined to be 600. At 95% confidence, the margin of error is ----------------------------------------------- E = ts/sqrt(n) --- E = t(0.975, df= 99)*50/sqrt(100) --- = 1.9842*50/10 --- = 9.9211.. ======================= Cheers, Stan H.
