You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly larger than 53% at a level of significance of a = 0.05. According to your sample, 43 out of 79 potential voters prefer the Democratic candidate. Use the p-value approach. a. For this study, we should use [z-test for a population proportion Or b. The null and alternative hypotheses would be: Ho: P H₁: p c. The test statistic z d. The p-value= e. The p-value is > ✓ α = f. Based on this, we should fail to reject B (please enter a decimal) (Please enter a decimal) (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the populaton proportion is significantly larger than 53% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is larger than 53% The data suggest the population proportion is not significantly larger than 53% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 53%. The data suggest the population proportion is not significantly larger than 53% at a = 0.05, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is larger than 53%.
