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? 619 628 1170 555 552 478 O What are the hypotheses? O A. Ho: u> 1000 hic O B. Ho: u= 1000 hic H:u< 1000 hic H:u< 1000 hic OC. Ho: u=1000 hic H u2 1000 hic O D. Ho: u<1000 hic Η. μ2 1000 hic Identify the test statistic. t=O (Round to three decimal places as needed.) Identify the P-value. The P-value is (Round to four decimal places as needed.) Click to select your answer(s).
Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
