Question 3

Question 3 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 we want to find the probability that on a single test, x is more than 7900, we need to calculate z value first. Complete the following (Round your answer to two decimal places.) P(x > 7900) = P(Z > (Round your answer to two decimal places.) Note: We will be using this result to answer Question 4
