Question 1056825: The level of calcium in the blood of healthy young adults follows a Normal distribution with mean μ = 10 milligrams per deciliter and standard deviation σ = 0.4. A clinic measures the blood calcium of 100 healthy pregnant young women at their first visit for prenatal care. The mean of these 100 measurements is = 9.8. Is this evidence that the mean calcium level in the population of healthy pregnant young women is less than 10? To answer this, test the hypotheses H0: μ = 10 versus Ha: μ < 10 at the 5% significance level.
What is the value of the P-value?
