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 = 4. A clinic measures the blood calcium of 25 healthy pregnant young women at their first visit for prenatal care. The mean of these 25 measurements is x̄ = 8.4. We want to test the hypotheses H0: μ = 10; HA: μ < 10. what="" does="" it="" mean="" if="" the="" p-value="" is="">
If the true population mean is 10, the probability that we get a sample mean of 8.4 or less is 0.0002.
If the true population mean is 10, the probability that we get a sample mean of 8.4 or more is 0.0002.
If the true population mean is 10, the probability that we get a sample mean of 8.4 is 0.0002.
If the sample mean is 8.4, the chance the population mean is 10 is 0.0002.
