Only 18% of registered voters voted in the last election. Will voter participation decline for the upcoming election? Of the 320 randomly selected registered voters surveyed, 54 of them will vote in the upcoming election. What can be concluded at the a = 0.01 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 V (please enter a decimal) H1: ?V Select an answer V (Please enter a decimal) c. The test statistic (please show your answer to 3 decimal places.)

The test statistic (please show your answer to 3 decimal places.) d. The p-value = e. The p-value is ?V a f. Based on this, we should Select an answer g. Thus, the final conclusion is that ... (Please show your answer to 4 decimal places.) ) the null hypothesis. The data suggest the population proportion is not significantly lower than 18% at a = 0.01, so there is statistically insignificant evidence to conclude that the percentage of registered voters who will vote in the upcoming election will be lower than 18%. O The data suggest the populaton proportion is significantly lower than 18% at a = 0.01, so there is statistically significant evidence to conclude that the the percentage of all registered voters who will vote in the upcoming election will be lower than 18%. O The data suggest the population proportion is not significantly lower than 18% at a = 0.01, so there is statistically significant evidence to conclude that the percentage of registered voters who will vote in the upcoming election will be equal to 18%.
