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 method of testing hypotheses. Company Auses 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 deviation for the old production method. If it appears that the standard deviation s greater, does the new production method appear to be better or worse than the old method? Should the company take any action?

Question
What are the null and alternative hypotheses?
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 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 deviation for the old production method. If it appears that the standard deviation s greater, does the new production method appear to be better or worse than the old method? Should the company take any action? What are the null and alternative hypotheses? O A. H, o=32.2 ft H, o+32.2 ft OB H, o>32 2 f H,: o= 322 ft O C. H, o<32.2 ft H, o=32.2 ft O D.

Expert Solution
Step 1

We have that :

Alpha = 0.05 

σ  = 32.2 ft. 

By using the hypothesis concept we make nupp and alternate hypothesis from given information.
