10 Suppose Jamal is studying poverty in his economics class, and he wants to compare the proportion of individuals living below the poverty line in the western United States in different years. He collects data on a simple random sample of people from 2013 and a simple random sample of people from 2014. His data are summarized in the table. Macmillan Learning Population Sample Number Proportion Population description size of successes of sucesses population in 2013 n1 = 486 X1 = 74 P1 = 0.15226 population in 2014 n2 = 490 X2 = 69 P2 = 0.14082 Jamal wants to run a two-sample z-test for the difference of two proportions to test the alternative hypothesis, H1 : P1 > P2, against the null hypothesis, Ho : P1 = P2, where pi is the proportion of population in 2013 that are living below the poverty line, and p2 is the proportion of population in 2014 that are living below the poverty line. Jamal selects a significance level of a = 0.10. Compute the z-statistic and P-value for Jamal's z-test for the difference of two proportions, P1 - P2. Give your answers precise to three decimal places. z-statistic = P-value = Based on your answers and a significance level of a = 0.10, complete the following sentences to state the decision and conclusion of Jamal's test. Jamal decides .... ... the hypothesis. The conclusion is that the proportion of the 2013 population living in poverty .. the proportion of the 2014 population living in poverty, because U O P S D F K C B N M command Option
