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? 797 662 1167 602 629 631 0 What are the hypotheses? O A. Hill = 1000 hic O B. Ha: pl > 1000 hic Hy: p 2 1000 hic Hy: H 0.5 O D. Ho: P = 0.5 Hy : p = 0.5 H1: p 0.5 Hy : p #0.5 What is the test statistic? z= (Round to two decimal places as needed. ) What is the P-value? P-value = (Round to three decimal places as needed.) What is the conclusion about the null hypothesis? O A. Reject the null hypothesis because the P-value is greater than the significance level, a. O B. Reject the null hypothesis because the P-value is less than or equal to the significance level, a. O C. Fail to reject the null hypothesis because the P-value is greater than the significance level, a. O D. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, a. What is the final conclusion? A. There is sufficient evidence to support the claim that most medical malpractice lawsuits are dropped or dismissed. O B. There is not sufficient evidence to support the claim that most medical malpractice lawsuits are dropped or dismissed. O C. There is sufficient evidence to warrant rejection of the claim that most medical malpractice lawsuits are dropped or dismissed. O D. There is not sufficient evidence to warrant rejection of the claim that most medical malpractice lawsuits are dropped or dismissed.Claim: A minority of adults would erase all of their personal information online if they could. A software firm survey of 678 randomly selected adults showed that 36% of them would erase all of their personal information online if they could. Complete parts (a) and (b) below. a. Express the original claim in symbolic form. Let the parameter represent the adults that would erase their personal information. (Type an integer or a decimal. Do not round.) b. Identify the null and alternative hypotheses. Ho: (Type integers or decimals. Do not round.)A genetic experiment involving peas yielded one sample of offspring consisting of 436 green peas and 166 yellow peas. Use a 0.01 significance level to test the claim that under the same circumstances, 26% of offspring peas will be yellow. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution. What are the null and alternative hypotheses? O A. Ho: P #0.26 O B. Ho: p#0.26 H1: p > 0.26 Hy : p 0.26 O E. Ho: p = 0.26 OF. Ho: P= 0.26 H1: p
