question 41

Essay

Use the traditional method to test the given hypothesis. Assume that the population is normally distributed and that the sample has been randomly selected. A manufacturer uses a new
production method to produce steel rods. A random sample of 17 steel rods resulted in lengths
with a standard deviation of 4.7 cm. At the 0.10 significance level, test the claim that the new
production method has lengths with a standard deviation different from 3.5 cm, which was the
standard deviation for the old method.
