Cesar wants to know what the expected weight of a loaf of bread for quality control purposes. Based on a sample of 14 loaves of bread, he finds a sample average of 400 grams with a sample standard deviation of 15 grams. What’s the confidence interval at 95%? What is it at 99.9%? What would the confidence intervals (for 95% and 99.9%) be if the sample average was based on 140 loaves instead of 14? Include the upper and lower bounds for each of the four intervals and be sure to include what you put into Excel to determine your answer. Round your answers to two decimal places.
