A news article that you read stated that 51% of voters prefer the Democratic candidate. You think that the actual percent is larger. 115 of the 217 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: Select an answer H: Select an answer c. The test statistic ?= d. The p-value = e. The p-value is ? a (please enter a decimal) (Please enter a decimal) (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) f. Based on this, we should Select an answer the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the populaton proportion is significantly larger 51% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is larger 51% The data suggest the population proportion is not significantly larger 51% at a = 0.05, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is larger 51%. The data suggest the population proportion is not significantly larger 51% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 51%. h. Interpret the p-value in the context of the study. There is a 27.83% chance of a Type I error. If the population proportion of voters who prefer the Democratic candidate is 51% and if another 217 voters are surveyed then there would be a 27.83% chance that more than 53% of the 217 voters surveyed prefer the Democratic candidate. If the sample proportion of voters who prefer the Democratic candidate is 53% and if another 217 voters are surveyed then there would be a 27.83% chance of concluding that more than 51% of all voters surveyed prefer the Democratic candidate. There is a 27.83% chance that more than 51% of all voters prefer the Democratic candidate.
