Assume that a simple random sample has been selected from a normally distributed population and test thegiven claim. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusionthat addresses the original claim.A safety administration conducted crash tests of child booster seats for cars. Listed below are results fromthose tests, with the measurements given in hic (standard head injury condition units). The safety requirementis that the hic measurement should be less than 1000 hic. Use a 0.01 significance level to test the claim thatthe sample is from a population-with a mean less than 1000 hic. Do the results suggest that all of the childbooster seats meet the specified requirement?7187651240668650627Identify the test statistic.t=(Round to three decimal places as needed.)Identify the P-value.The P-value is(Round to four decimal places as needed.)State the final conclusion that addresses the original claim.Ho.

Use the technology display, which results from the head injury measurements from car crash dummies listed below. The measurements are in hic (head injury criterion) units, and they are from the same cars used for the table below. Use a 0.01 significance level to test the given claim. Test the null hypothesis that head injury measurements are not affected by an interaction between the type of car (foreign, domestic) and size of the car (small, medium, large). What do you conclude? Click the icon to view the data table and technology display. What are the null and alternative hypotheses? O A.
