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. Asafety administration conducted crash tests of child booster seatsfor cars. Listed below are results from those​ tests, with themeasurements given in hic​ (standard head injury condition​ units).The safety requirement is that the hic measurement should be lessthan 1000 hic. Use a 0.05 significance level to test the claim thatthe sample is from a population with a mean less than 1000 hic. Dothe results suggest that all of the child booster seats meet thespecified​ requirement? 669 635 1144 661 600 749
