sample standard deviation of 3%. Using a=0.10 significance level, test the poverty had further declined in 2018 from the previous year. 12. Clearly restate the claim associated with this test and state the null and alternate hypotheses. 13. Provide two or three sentences to state the type of test that should be performed based on the hypotheses. Additionally, state the assumptions and conditions that justify the appropriateness of the test. 14. Use technology to identify, and then provide the test statistic and the resulting P-value associated with the given sample results. Provide a statement (1-2 sentences) that explains the interpretation of the P-value. (Print or copy-and-paste the output that identified these values, or any other form of evidence that technology was used.) 15. State, separately, both the decision/result of the hypothesis test, and the appropriate conclusion/statement about the claim. (1-2 sentences for each). Poverty percentage

Question
Although poverty was still of great concern in the United States, some politicians claimed that the recovery from the Great Recession was noticeable, and that the poverty rate had been steadily declining especially in recent years. In 2017, the national poverty rate was 13.4%. It was believed that the national percent of people in poverty was even lower in 2018 than it was in 2017. To support this belief, a 2018 sample of n-16 jurisdictions produced a sample mean of 12.36% for the percent of people in poverty, with a sample standard deviation of 3%. Using a=0.10 significance level, test the claim that the national average percent of people in poverty had further declined in 2018 from the previous year. 12. Clearly restate the claim associated with this test and state the null and alternate hypotheses. 13. Provide two or three sentences to state the type of test that should be performed based on the hypotheses. Additionally, state the assumptions and conditions that justify the appropriateness of the test. Part 3: Hypothesis Testing 14.
