Question 23

Use the Hypothesis Testing: Procedure for Hypothesis Tests flow chart interactive to answer the following question. In conducting a hypothesis test of the claim that p > 0.4, the critical value is z = 2.33 and the test statistic is 2.22. Which one of the following is the correct decision stated in nontechnical terms? Choose the correct answer below. O A. There is not sufficient evidence to reject the claim that p > 0.4. O B. There is not sufficient evidence to support the claim that p > 0.4. O C. There is sufficient evidence to reject the claim that p > 0.4. O D. There is sufficient evidence to support the claim that p > 0.4.K The claim is that weights (grams) of quarters made after 1964 have a mean equal to 5.670 g as required by mint specifications. The sample size is n = 37 and the test statistic is t= - 2.987. Use technology to find the P-value. Based on the result, what is the final conclusion? Use a significance level of 0.10. State the null and alternative hypotheses. Ho- H (Type integers or decimals. Do not round.) The test statistic is (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.) Based on the P-value, there sufficient evidence at a significance level of 0. 10 to the claim that weights of quarters made after 1964 have a mean equal to 5.670 g as required by mint specifications.Consider a sample of 52 football games, where 27 of them were won by the home team. Use a 0.01 significance level to test the claim that the probability that the home team wins is greater than one-half Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho P= 0.5 Hy p > 0.5 O B. Ho P=0.5 Hy : p #0.5 O C. Ho: P > 0.5 H1 p= 0.5 O D. Ho P=05 Hy: p 0.5 Hy : p = 0.5 O D. Ho: P= 0.5 Hy : p
