Test the given claim. Assume that a simple random sample is selected from a normally distributed population. Use either the P-value method or the traditional What are the null and alternative hypotheses? method of testing hypotheses. Company A uses a new production method to manufacture aircraft altimeters. A simple random sample of new altimeters resulted in errors listed below. Use a 0.05 level of significance to test the claim that the new production method has errors with a standard deviation greater than 32.2 ft, which was the standard O A. Ho: 6 = 32.2 ft O B. H: 6> 32.2 ft deviation for the old production method. If it appears that the standard deviation is greater, does the new production method appear to be better or worse than the H,: 6#32.2 ft H,: 6 = 32.2 ft old method? Should the company take any action? YC. Ho: 6 = 32.2 ft O D. Ho: 6 32 2 ft H.: 6 = 32.2 ft O E. Ho: 6 = 32.2 ft OF. Ho: 0#32.2 ft H,: 6
