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 = 0.10. According to your sample, 62 out of 80 potential voters prefer the Democratic candidate.

1. For this study, we should use Select an answer z-test for a population proportion t-test for a population mean
2. The null and alternative hypotheses would be: Ho: ? p Select an answer = > < (please enter a decimal) H₁: ? p Select an answer < = > (Please enter a decimal)
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 ? >
6. Based on this, we should Select an answer accept fail to reject reject the null hypothesis.
7. Thus, the final conclusion is that ...
8. Interpret the p-value in the context of the study.
9. Interpret the level of significance in the context of the study.

• If the population proportion of voters who prefer the Democratic candidate is 75% and if another 80 voters are surveyed then there would be a 10% chance that we would end up falsely concluding that the proportion of voters who prefer the Democratic candidate is different from 75%
• If the proportion of voters who prefer the Democratic candidate is different from 75% and if another 80 voters are surveyed then there would be a 10% chance that we would end up falsely concluding that the proportion of voters who prefer the Democratic candidate is equal to 75%.
• There is a 10% chance that the proportion of voters who prefer the Democratic candidate is different from 75%.
• There is a 10% chance that the earth is flat and we never actually sent a man to the moon.

• There is a 60.56% chance of a Type I error.
• If the sample proportion of voters who prefer the Democratic candidate is 77% and if another 80 voters are surveyed then there would be a 60.56% 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.
• There is a 60.56% chance that the percent of all voters who prefer the Democratic candidate differs from 75%.
• If the population proportion of voters who prefer the Democratic candidate is 75% and if another 80 voters are surveyed then there would be a 60.56% chance that either more than 77% of the 80 voters surveyed prefer the Democratic candidate or fewer than 73% of the 80 voters surveyed prefer the Democratic candidate.

• The data suggest the population proportion is not significantly different from 75% at = 0.10, so there is not 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 = 0.10, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 75%.
• The data suggest the populaton proportion is significantly different from 75% at = 0.10, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different from 75%
