3) You are given the claim that the mean of a population is not equal to 24 cm. You don’t believe in this claim and so you want to test it. Suppose that you know the population standard deviation is 4 cm, and the population distribution is approximately normal. To test this claim, you take a random sample as follows X = (20, 23, 22, 24, 24, 24, 25, 26, 24, 23, 27, 24, 29, 20, 25, 26, 28). Is...

Exhibit 10-9 Two major automobile manufacturers have produced compact cars with the same size engines. We are interested in determining whether or not there is a significant difference in the MPG (miles per gallon) of the two brands of automobiles. A random sample of eight cars from each manufacturer is selected, and eight drivers are selected to drive each automobile for a specified distance. The following data show the results of the test. Driver Manufacturer A Manufacturer B 1 32...
