Suppose the level of calcium in the blood in healthy young adults varies with mean about 9.6 milligrams per deciliter and standard deviation about σ = 0.3. A clinic in rural Guatemala measures the blood calcium level of 140 healthy pregnant women at their first visit for prenatal care. The mean is x = 9.67. Is this an indication that the mean calcium level in the population from which these women come differs from 9.6?
