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 0.05 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?

Identify the test statistic.
State the final conclusion that addresses the original claim.
(Reject or Fail to reject) H0. There is (sufficient or insufficient) evidence to support the claim that the sample is from a population with a mean less than 1000 hic.
What do the results suggest about the child booster seats meeting the specified requirement?
A.There is strong evidence that the mean is less than 1000 hic, but one of the booster seats has a measurement that is greater than 1000 hic.
B.The requirement is met since most sample measurements are less than 1000 hic.
C. The results are inconclusive regarding whether one of the booster seats could have a measurement that is greater than 1000 hic.
D.There is strong evidence that the mean is less than 1000 hic, and one of the booster seats has a measurement that is greater than 1000 hic.

Assume that a simple random sample has been selected from a
normally distributed population and test the given claim. Use
either the traditional method or P-value method as indicated.
Identify the null and alternative hypotheses, test statistic,
critical value(s) or P-value (or range of P-values) as appropriate,
and state the final conclusion that addresses the original
claim.
Use a significance level of α = 0.01 to test the claim that μ
