You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly different from 62% at a level of significance of a = 0.05. According to your sample, 27 out of 50 potential voters prefer the Democratic candidate. a. For this study, we should use [z-test for a population proportion b. The null and alternative hypotheses would be: Ho: pv = 0.62 H₁: p V 0.62 (please enter a decimal) (Please enter a decimal) c. The test statistic z=-1.165 d. The p-value= e. The p-value is ? a f. Based on this, we should Select an answer the null hypothesis. g. Thus, the final conclusion is that ... (please show your answer to 3 decimal places.) I(Please show your answer to 4 decimal places.)

Os #3 Microsoft Word -... You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly different from 62% at a level of significance of a = 0.05. According to your sample, 27 out of 50 potential voters prefer the Democratic candidate. E a. For this study, we should use [z-test for a population proportion b. The null and alternative hypotheses would be: Ho: p= ✓0.62 (please enter a decimal) H₁: p (Please enter a decimal) c. The test statistic z = -1.165 (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) d. The p-value = Ï e. The p-value is ? a f. Based on this, we should Select an answer the null hypothesis. g. Thus, the final conclusion is that ... 80 F3 O The data suggest the populaton proportion is significantly different from 62% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different from 62% O The data suggest the population proportion is not significantly different from 62% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 62%. O The data suggest the population proportion is not significantly different from 62% at a = 0.05, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different from 62%. h. Interpret the p-value in the context of the study. O There is a 24.38% chance that the percent of all voters who prefer the Democratic candidate differs from 62%. O There is a 24.38% chance of a Type I error. O If the sample proportion of voters who prefer the Democratic candidate is 53% and if another 50 voters are surveyed then there would be a 24.38% chance that we would conclude either fewer than 62% of all voters prefer the Democratic candidate or more than 62% of all voters prefer the Democratic candidate. O If the population proportion of voters who prefer the Democratic candidate is 62% and if another 50 voters are surveyed then there would be a 24.38% chance that either fewer than 53% of the 50 voters surveyed prefer the Democratic candidate or more than 71% of the 50 voters surveyed prefer the Democratic candidate. i.
