Voters are in the mood to explore the four electoral districts to compare the interests of votes per candidate. Voters random sample of 200 people were surveyed in four fields, which are shown in Table 14.9 Values in parentheses is the number of cells to be expected. Data presented sufficient evidence to indicate that the favorite of votes per candidate A is the difference in the four districts? Table 14.9 Opinion of the vote in the four county area 1 District 2 District 3 District 4 includes the likes A 76 (59). 53 (59) 59 (59) 48 (59) 236 Dislikes a 124 (141) 147 (141) 141 (141) 152 (141) 564 200 200 200 200 800 do when the column was set at 200. binomial model is four trials. Each trial was the result of the vote, 200 people from one of the four zones to test the equivalence of the proportion of people who prefer candidate A in four districts hypothesis is Ho: p1 = p2 = p3 = p4 , which is comparable to the hypothesis Ho:. the proportion preference candidate a is not on the field , and will be rejected if the test statistic X2 great value observed of statistical tests X2 = 10.722 and p =. 013 is shown in Figure 14.5, the effect is significant (p. <0.025) that Ho is rejected and you can conclude that there is no difference in the proportion of voters who prefer candidate a on the four themes of 14.5 MINITAB for example. 14.7 chi-squared test: Zone 1, Zone 2, Zone 3, Zone 4 different characteristics found by chi-squared test is? To answer this question, see Table 14.10, which shows the proportion of the sample who prefer candidate A in each county to see that candidate A is best done in the first and worst in the fourth, then it means in practice for applicants. or not? It is possible that even more notable is that the candidate has a majority in any district. If this is the second race of the candidate A candidate must campaign to increase the proportion of 14.10 square inclination A candidate in District 4 District 1 District 2 District 3 District 4 = 0.38 76/200 53/200 59/200 = 0.27. 48/200 = 0.30 = 0.24
