You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly different from 50% at a level of significance of a = 0.01. According to your sample, 39 out of 94 potential voters prefer the Democratic candidate. a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? ? (please enter a decimal) | (Please enter a decimal) c. The test statistic 2 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.) (Please show your answer to 4 decimal places.) O The data suggest the population proportion is not significantly different from 50% at a = 0.01, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different from 50%. O The data suggest the population proportion is not significantly different from 50% at a = 0.01, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 50%. The data suggest the populaton proportion is significantly different from 50% at a = 0.01, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different from 50%
