Question 1 The lengths of metal rods produced by an industrial process are normally distributed with a standard deviation of 1.8 millimeters. Based on a random sample of nine observations from this population, the 99% confidence interval was found for the population mean length to extend from 194.65 to 197.75. Suppose that a production manager believes that the interval is too wide for practical use and, instead, requires a 99% confidence interval extending no further than 0.50 mm on each...
