Assume that a simple random sample has been selected from anormally distributed population and test the given claim. Identifythe null and alternative​ hypotheses, test​ statistic, P-value, andstate the final conclusion that addresses the original claim.
A safety administration conducted crash tests of child boosterseats for cars. Listed below are results from those​ tests, withthe measurements given in hic​ (standard head injury condition​units). The safety requirement is that the hic measurement shouldbe less than 1000 hic. Use a 0.010.01 significance level to testthe claim that the sample is from a population with a mean lessthan 1000 hic. Do the results suggest that all of the child boosterseats meet the specified​ requirement?
