They have the control over every process to produce potato chips from farming of potatoes to distribution of the final product to the retail stores. It would be inspected at least 11 times during the process. In addition to that, firm uses proprietary vision system to find the defective potato chips. Standards quoted by Country A institute of baking is strictly followed by the firm to produce quality products.

- Quality Control of Doughnuts: The Hudson Valley Bakery makes doughnuts that are packaged in boxes with labels stating that there are 12 doughnuts weighing a total of 42 oz. If the variation among the doughnuts is too large, some boxes will be underweight (cheating consumers) and others will be overweight (lowering profit). A consumer would not be happy with a doughnut so small that it can be seen only with an electron microscope, nor would a consumer be happy with a doughnut so large that it resembles a tractor tire. The quality-control supervisor has found that he can stay out of trouble if the doughnuts have a mean of 3.50 oz. and a standard deviation of 0.06 oz. or less. Twelve doughnuts are randomly selected from the production line and weighed, with the result given here (in ounces). 3.43 3.37 3.58 3.50 3.68 3.61 3.42 3.52 3.66 3.50 3.36 3.42 Construct a 95% confidence interval for σ, and then determine whether the quality-control…arrow_forwardconcernedas to whether caulking tubes are being properly capped.
