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?
810 738 1216 658 606 544

A.
H0​: μ=1000 hic
H1​: μ<1000 hic
B.
H0​: μ=1000 hic
H1​: μ≥1000 hic
C.
H0​: μ<1000 hic
H1​: μ≥1000 hic
D.
H0​: μ>1000 hic
H1​: μ<1000 hic
(I also need the test statistic and p-value) thank you in advance :)
