Workers at a large toxic cleanup project are concerned that their white blood cell counts may have been reduced. Let x be a random variable that represents white blood cell count per cubic millimeter of whole blood in a healthy adult. Then u = 7500 and o = 1750.t A random sample of n = 50 workers from the toxic cleanup site were given blood test that showed x = 6850.

Workers at a large toxic cleanup project are concerned that their white blood cell counts may have been reduced. Let x be a random variable that represents white blood cell count per cubic millimeter of whole blood in a healthy adult. Then u = 7500 and o = 1750.† A random sample of n = 50 workers from the toxic cleanup site were given a blood test that showed x = 6850. What is the probability that, for healthy adults, x will be this low or lower? In USE SALT (a) How does the central limit theorem apply? Explain. The central limit theorem describes the distribution of x as normal with mean u - = 7500 and o ,z 35.00. The central limit theorem describes the distribution of x as normal with mean u, = 7500 and o , - 247.49. The central limit theorem does not apply because the sample size is too small. The central limit theorem describes the distribution of x as normal with mean u, 7500 and z 1750.00. (b) Compute P(x < 6850). (Round your answer to four decimal places.) P(x < 6850) %3D (c) Based on your answer to part (b), would you recommend that additional facts be obtained, or would you recommend that the workers' concerns be dismissed? Explain.
