NEED HELP WITh: E, F G,H, I

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 = 0.05. According to your sample, 56 out of 100 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: ? O ? (please enter a decimal) H1: ? (Please enter a decimal) ? c. The test statistic ? (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 Select an answer O the null hypothesis. g. Thus, the final conclusion is that ... OThe data suggest the populaton proportion is significantly different from 50% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different from 50% OThe data suggest the population proportion is not significantly different from 50% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 50%. OThe data suggest the population proportion is not significantly different from 50% 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 50%. h. Interpret the p-value in the context of the study. OIf the sample proportion of voters who prefer the Democratic candidate is 56% and if another 100 voters are surveyed then there would be a 23.02% chance that we would conclude either fewer than 50% of all voters prefer the Democratic candidate or more than 50% of all voters prefer the Democratic candidate. OThere is a 23.02% chance that the percent of all voters who prefer the Democratic candidate differs from 50%.
