Aproduction process fills containers by weight. weights of containers are approximately normally distributed. historically, the standard deviation of weights is 5.5 ounces. (this standard deviation is therefore known.) a quality control expert selects n containers at random. how large a sample would be required in order for the 99% confidence interval for to have a length of 2 ounces?
