Capstone Project Part 2

In the automated packaging process, equipment is set to fill boxes with a mean weight of 285 grams. This is the standard for the population. Population standard deviation is not known. 1. Calculate a 95% confidence interval for the mean weight of the cereal boxes, using the sample data given in the Excel spreadsheet labeled Cereal Weights. 2. Based on the confidence interval for the mean weight of cereal boxes, does this sample of 500 boxes provide evidence that the packaging process is meeting the company standard? Explain. 0 3. The company engineer made adjustments to the filling equipment, including recalibrating the weighers (scales), in an attempt to correct the issue. A random sample of 90 boxes was selected and weighed after the adjustments. The data for this sample can be found in the
