A researcher collected sample data for 14 women ages 18 to 24. The sample had a mean serum cholesterol level (measured in mg/100 mL) of 188.1, with a standard deviation of 6.8. Assuming that serum cholesterol levels for women ages 18 to 24 are normally distributed, find a 95% confidence interval for the mean serum cholesterol level of all women in this age group. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round...

In a large hospital, a nursing director selected a random sample of 38 registered nurses and found that the mean of their ages was 31.9. The population standard deviation for the ages is 4.2. She selected a random sample of 28 nursing assistants and found the mean of their ages was 29.5. The population standard deviation of the ages for the assistants is 6.0. Find the 99% confidence interval of the differences in the ages. Use μ1 for the mean...
