Question

You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly smaller than 62% at a level of significance of � = 0.01. According to your sample, 54 out of 89 potential voters prefer the Democratic candidate.

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

The test statistic Correct = Incorrect (please show your answer to 3 decimal places.)
The p-value = Incorrect (Please show your answer to 4 decimal places.)
The p-value is Correct �
Based on this, we should Correct the null hypothesis.
Thus, the final conclusion is that ...
- The data suggest the population proportion is not significantly smaller than 62% at � = 0.01, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 62%.
- The data suggest the population proportion is not significantly smaller than 62% at � = 0.01, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is smaller than 62%.
- The data suggest the populaton proportion is significantly smaller than 62% at � = 0.01, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is smaller than 62%
Incorrect
Interpret the p-value in the context of the study.
- There is a 62% chance of a Type I error.
- If the sample proportion of voters who prefer the Democratic candidate is 61% and if another 89 voters are surveyed then there would be a 39.83% chance of concluding that fewer than 62% of all voters surveyed prefer the Democratic candidate.
- There is a 39.83% chance that fewer than 62% of all voters prefer the Democratic candidate.
- If the population proportion of voters who prefer the Democratic candidate is 62% and if another 89 voters are surveyed then there would be a 39.83% chance fewer than 61% of the 89 voters surveyed prefer the Democratic candidate.
Correct
Interpret the level of significance in the context of the study.
- If the proportion of voters who prefer the Democratic candidate is smaller than 62% and if another 89 voters are surveyed then there would be a 1% chance that we would end up falsely concluding that the proportion of voters who prefer the Democratic candidate is equal to 62%.
- There is a 1% chance that the proportion of voters who prefer the Democratic candidate is smaller than 62%.
- There is a 1% 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 62% and if another 89 voters are surveyed then there would be a 1% chance that we would end up falsely concluding that the proportion of voters who prefer the Democratic candidate is smaller than 62%
