Test the given claim. Assume that a simple random sample is selected from a normally distributed population. Use either theP-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 32.2ft, which was the standard deviation for the old production method. If it appears that the standard deviation isgreater, does the new production method appear to be better or worse than the oldmethod? Should the company take anyaction?

-40, 77, -22, -72, -44, 12, 18, 53, -5, -54, -107, -107

Correct Hypotheses?

T-Statistic?

P-Value?

Conclusions? (i.e. reject/fail to reject due to..., etc...)

I am given StatCrunch to use in order to solve the problems.

If you are able to show me how to answer the given problem and explain it to be I would be very grateful.
