Jamestown Steel Company manufactures and assembles desks and other office equipment at several plants in western New York State. The weekly production of the Model A325 desk at the Fredonia Plant follows the normal probability distribution with a mean of 200 and a standard deviation of 16. Recently, because of market expansion, new production methods have been introduced and new employees hired. The vice president of manufacturing would like to investigate whether there has been a change in the weekly production of the Model A325 desk. Suppose he wants the significance level to be 0.01. denote %u03BC to be the population mean of weekly production of the Model A325 after new methods, set up the null hypothesis the vice president wants to test:

a. %u03BC = 200

b. %u03BC %u2260 200

c. %u03BC > 200

d. %u03BC < 200

e. %u03BC %u2264 200
