A company that produces white bread is concerned about the distribution of the amount of sodium in its bread. The company takes a simple random sample of 55 slices of bread and computes the mean of the sample is to be 103 milligrams of sodium per slice. We want to construct a 99% confidence interval for the unknown mean sodium level assuming that the population standard deviation is 10 milligrams. The standard error is ["", "", "", ""] . The margin of error E= ["", "", "", ""] f) The 99% confidence interval for the population mean sodium level in each slice of bread is ["", "", "", ""] . g) if we increase the sample size to 150, the 99% confidence interval will become ["", "", ""] .
