You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly smaller than 70% at a level of significance of a = 0.01. According to your sample, 56 out of 84 potential voters prefer the Democratic candidate. a. For this study, we should use z-test for a population proportion v b. The null and alternative hypotheses would be: Ho: ?v Select an answer ♥ (please enter a decimal) H1: ?v Select an answer ♥ (Please enter a decimal) c.

Please answer B, C, & D. 

You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly smaller than 70% at a level of significance of a = 0.01. According to your sample, 56 out of 84 potential voters prefer the Democratic candidate. a. For this study, we should use z-test for a population proportion v b. The null and alternative hypotheses would be: Ho: ?v||Select an answer v (please enter a decimal) H1: ? v|Select an answer v (Please enter a decimal) c. The test statistic ?v = (please show your answer to 3 decimal places.) d. The p-value = |(Please show your answer to 4 decimal places.) e. The p-value is f. Based on this, we should fail to reject the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the population proportion is not significantly smaller than 70% at a = 0.01, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 70%. O The data suggest the population proportion is not significantly smaller than 70% at a = 0.01, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is smaller than 70%. The data suggest the populaton proportion is significantly smaller than 70% at a = 0.01, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is smaller than 70%
