The distribution of hours of sleep for newborns is normally distributed with a mean = 15.5 Hours and A standard deviation= 1.6 hours. What is the greatest amount of time that a newborn can sleep and still be in the bottom 75% of newborn sleep times?
A sample of 77 subjects went on a low-carbohydrate diet for six months. At the end of that time, the sample mean weight loss was 4.7 kilograms with a sample standard deviation of 7.16 kilograms. A second sample of 79 subjects went on a low-fat diet. Their sample mean weight loss was 2.6 kilograms with a standard deviation of 5.90 kilograms. Can you conclude that the mean weight loss differs between the two diets? Use a = 0.01. Use the critical value method.
Suppose that the quarterly sales levels among health care information systems companies are approximately normally distributed with a mean of 10 million dollars and a standard deviation of 1.2 million dollars. One health care information systems company considers a quarter a "failure" if its sales level that quarter is in the bottom 15% of all quarterly sales levels. Determine the sales level (in millions of dollars) that is the cutoff between quarters that are considered "failures" by that company and quarters that are not. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place. ☐ million dollars X 5
