Describe the special treatment required for milk
What will be an ideal response?
Mechanical refrigeration begins to cool it even during milking, from 90 to 50oF within the first hour and from 50 to 40oF within the next hour. As more milk is added, the blended liquid must not rise above 45oF. Milk is stored in insulated or refrigerated silo type tanks that maintain a 40oF temperature. After milk is pasteurized and homogenized it is again cooled in a heat exchanger

The article “Treadmill Exercise and Resistance Training in Patients With Peripheral Arterial Disease With and Without Intermittent Claudication. A Randomized Controlled Trial” reported the results of a study to determine whether treadmill exercise could improve the walking ability of patients suffering from claudication, which is pain caused by insufficient blood flow to the muscles of the legs. A sample of 48 patients walked on a treadmill for six minutes every day. After six months, the mean distance walked in six minutes was 348m, with a standard deviation of 80m. For a control group of 46 patients who did not walk on a treadmill, the mean distance was 309 m with a standard deviation of 89 m. Find a 95% confidence interval for the difference in mean distance walked between the two
groups of patients. What will be an ideal response?
