5. The level of calcium in the blood in healthy young adults varies with a mean of about 9.5 mg per liter and standard deviation of about 0.4. A clinic in rural Guatemala measures the blood calcium of 180 healthy pregnant women at their first visit for prenatal care. The mean is 9.58. Is this an indication that the mean calcium level from which these women come is greater than 9.5? (Assume s = 0.4) a. Give a 90% confidence...

My Ask You C-reactive protein (CRP) is a substance that can be measured in the blood. Values increase substantially within & hours of an infection and reach a peak within 24 to 48 hours after. In adults, chronically high values have been linked to an increased risk of cardiovascular disease. In a study of apparently healthy children aged 6 to 60 months in Papua New Guinea, CRP was measured in 90 children. The units are milligrams per liter (mg/l). Here...
