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 is 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? -44 79 -21 -72 -42 15 16 51 -6 -52 -108 -108

Assume that a simple random sample has been selected from a
normally distributed population and test the given claim. Identify
the null and alternative hypotheses, test statistic, P-value, and
state the final conclusion that addresses the original claim. A
safety administration conducted crash tests of child booster seats
for cars. Listed below are results from those tests, with the
measurements given in hic (standard head injury condition units).
The safety requirement is that the hic measurement should be less
