You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly different from 75% at a level of significance of a = 0.01. According to your sample, 62 out of 78 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: ? v Select an answer v (please enter a decimal) H1: ? 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 ? va f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the population proportion is not significantly different from 75% at a = 0.01, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 75%. O The data suggest the populaton proportion is significantly different from 75% at a = 0.01, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different from 75% The data suggest the population proportion is not significantly different from 75% 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 75%. h. Interpret the p-value in the context of the study. O There is a 36% chance of a Type I error. O If the population proportion of voters who prefer the Democratic candidate is 75% and if another 78 voters are surveyed then there would be a 36% chance that either more than 79% of the 78 voters surveyed prefer the Democratic candidate or fewer than 71% of the 78 voters surveyed prefer the Democratic candidate. O There is a 36% chance that the percent of all voters who prefer the Democratic candidate differs from 75%. O If the sample proportion of voters who prefer the Democratic candidate is 79% and if another 78 voters are surveyed then there would be a 36% chance that we would conclude either fewer than 75% of all voters prefer the Democratic candidate or more than 75% of all voters prefer the Democratic candidate.
