Question

For this study, we should use
The null and alternative hypotheses would be:
Ho: (please enter a decimal)
H₁: (Please enter a decimal)

The test statistic = (please show your answer to 3 decimal places.)
The p-value = (Please show your answer to 4 decimal places.)
The p-value is αα
Based on this, we should the null hypothesis.
Thus, the final conclusion is that ...
- The data suggest the population proportion is not significantly different 53% at αα = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 53%.
- The data suggest the population proportion is not significantly different 53% at αα = 0.05, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different 53%.
- The data suggest the populaton proportion is significantly different 53% at αα = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different 53%
Interpret the p-value in the context of the study.
- If the population proportion of voters who prefer the Democratic candidate is 53% and if another 257 voters are surveyed then there would be a 5.74% chance that either fewer than 47% of the 257 voters surveyed prefer the Democratic candidate or more than 59% of the 257 voters surveyed prefer the Democratic candidate.
- If the sample proportion of voters who prefer the Democratic candidate is 47% and if another 257 voters are surveyed then there would be a 5.74% chance that we would conclude either fewer than 53% of all voters prefer the Democratic candidate or more than 53% of all voters prefer the Democratic candidate.
- There is a 5.74% chance that the percent of all voters who prefer the Democratic candidate differs from 53%.
- There is a 5.74% chance of a Type I error.
Interpret the level of significance in the context of the study.
- If the proportion of voters who prefer the Democratic candidate is different 53% and if another 257 voters are surveyed then there would be a 5% chance that we would end up falsely concluding that the proportion of voters who prefer the Democratic candidate is equal to 53%.
- There is a 5% chance that the earth is flat and we never actually sent a man to the moon.
- If the population proportion of voters who prefer the Democratic candidate is 53% and if another 257 voters are surveyed then there would be a 5% chance that we would end up falsely concluding that the proportion of voters who prefer the Democratic candidate is different 53%
- There is a 5% chance that the proportion of voters who prefer the Democratic candidate is different 53%.
