A bakery produces a certain type of bread in an oven that stacks trays nine high. The specification for the moisture content of finished loaves is 11% + 2%. Samples are taken by selecting a loaf at random from each tray. The results of 30 such samples are shown in the table.

c. Compute an estimate of the percentage of baked loaves that will be too moist. Compute an estimate of the percentage of loaves that will be too dry.

a different way-stratifying them by tray level. The Following table reflects this restoring.

ii. Is there any evidence that the moisture contents is affected by oven level? Explain.
iii. Is there any evidence that the moisture content is affected by oven level? Explain.
iv. Assuming that it is possible to center the process average at the target of 11% for each tray level, what is your estimate of the percentage of loaves that will be too dry and too moist? How does this answer compare to the one you obtained in part c?
