Question

Only 13% of registered voters voted in the last election. Will voter participation change for the upcoming election? Of the 306 randomly selected registered voters surveyed, 55 of them will vote in the upcoming election. What can be concluded at the αα = 0.10 level of significance?

For this study, what sampling distribution would be used? Select an answer -

1. Student's t distribution
2. binomial distribution
3. uniform distribution
4. standard normal distribution

The null and alternative hypotheses would be:

H0:

H1:

3. The test statistic ? t z  =  (please show your answer to 3 decimal places.)
4. The p-value =  (Please show your answer to 4 decimal places.)
5. The p-value is ? > or ≤  
6. Based on this, we should ______ the null hypothesis.
7. Thus, the final conclusion is that ...
   • The data suggest the populaton proportion is significantly different from 13% at αα = 0.10, 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 different from 13%.
   • The data suggest the population proportion is not significantly different from 13% at αα = 0.10, 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 13%.
   • The data suggest the population proportion is not significantly different from 13% at αα = 0.10, so there is statistically insignificant evidence to conclude that the percentage of registered voters who will vote in the upcoming election will be different from 13%.
