Question: 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,

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 than 1000 hic. Use a 0.01 significance level to test the claim that the sample is from a population with a mean less than 1000 hic. Do the results suggest that all of the child booster seats meet the specified requirement? 745 790 1383 675 668 503 5 What are the hypotheses? Ho: #= 1000 hic \"B. Ho: p= 1000 hic H4: p2 1000 hic Hy: p
