In the article "Evaluation variability in filling operations" (Food Technology [1984]: 51-55), a packaging process for ground beef was considered over a series of days. An important question is whether the true mean amount delivered by this process changes from day to day. Ten packages were accurately weighed and randomly selected over the course of the day. This was done on different packages also on the consecutive day. The results were: First Day (g per package): 1397.8 1394.8 1385.3 1391.7 1400.1 1391.2 1393.5 1385.7 1384.0 1391.0 Second Day (g per package): 1410.0 1393.9 1402.5 1405.9 1399.9 1404.2 1398.5 1387.3 1391.8 1392.5 Are these data paired or independent samples? b State the summary statistics associated with the data above. Test the hypothesis that the true mean amount changes from the first day to the second day. Use a significance level of 0.05. Show all steps clearly
