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? 727 778 1400 693 635 537 What are the hypotheses? A. Ho = 1000 hic OB. Ho H₁ <1000 hic > 1000 hic <1000 hic H₁ OC. Ho <1000 hic OD. Ho u 1000 hic H₁ 2 1000 hic Họ g a 1000 hic Identify the test statistic t=(Round to three decimal places as needed)
Px Recall that x was found earlier. Identify the values of s, n, and H.
To find the P-value, note that a t distribution table can be used to find a range, but for the purposes of this explanation, use technology to find an exact P-value To find the P-value, use df-n-1 for the number of degrees of freedom, where n is the sample size. Compute df.
