A potato chip company wants to evaluate the accuracy of its potato chip bag-filling machine. Bags are labeled as containing 8 ounces of potato chips. A simple random sample of 12 bags had mean weight 7.81 ounces with a sample standard deviation of 0.013 ounce. Assume the weights are approximately normally distributed. Construct a 90% confidence interval for the population mean weight of bags of potato chips. Round the answers to at least two decimal places. The 90% confidence interval is 00. G
