Question 5

Question 5 0 / 1 pts Let x be a random variable that represents white blood cell count per cubic milliliter of whole blood. Assume that x has a distribution that is approximately normal, with mean u = 7350 and estimated standard deviation o = 2950. Suppose a doctor uses the average x for three tests taken about a week apart and the probability distribution of is approximately normal. What is the probability that is less than 7900. Find the z value. P(x bar
