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, tost 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 0.05 significance level to test the claim that the sample is from a population with a mean less than 1000 hic. Do the rosults suggest that all of the child booster seats meet the specified requirement? 787 689 1149 661 644 660 What are the hypotheses? OA Ho: h=1000 hic | Hộ Hệ 1000 hic. OC Ho: > 1000 hic Hyu< 1000 hic Identify the test statistic t=(Round to three decimal places as needed.) 8. Ho: u = 1000 hic Hệ | < 1000 học OD. Ho: < 1000 hic HỊ Hà 1000 học
