Hi, please only complete C & E. Everything else is done, thank you.
Only 12% of registered voters voted in the last election. Will voter participation decline for the upcoming election? Of the 337 randomly selected registered voters surveyed, 24 of them will vote in the upcoming election. What can be concluded at the a = 0.05 level of significance? a. For this study, we should use z-test for a population proportion ✓ b. The null and alternative hypotheses would be: Ho: pv H₁: pv < c. The test statistic z v d. The p-value = e. The p-value is v f. Based on this, we should reject g. Thus, the final conclusion is that ... α 0.12 0.12 ✓(please enter a decimal) ✓(Please enter a decimal) = 2.768 X (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) the null hypothesis. O The data suggest the population proportion is not significantly lower than 12% at a = 0.05, 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 12%. O The data suggest the population proportion is not significantly lower than 12% at a = 0.05, 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 12%. The data suggest the populaton proportion is significantly lower than 12% at a = 0.05, 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 12%.
