Question
You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is
significantly smaller than 74% at a level of significance of a = 0.01. According to your sample, 55 out of 79
potential voters prefer the Democratic candidate.
a. For this study, we should use [Select an answer
b. The null and alternative hypotheses would be:
Ho: ? Select an answer
H₁: ? ✓ Select an answer
c. The test statistic ? ✓
=
d. The p-value =
e. The p-value is ? ✓ a
f. Based on this, we should
g. Thus, the final conclusion is that ...

(Please show your answer to 4 decimal places.)
Select an answer the null hypothesis.
O The data suggest the populaton proportion is significantly smaller than 74% at a = 0.01, so
there is sufficient evidence to conclude that the proportion of voters who prefer the
Democratic candidate is smaller than 74%
O The data suggest the population proportion is not significantly smaller than 74% at a = 0.01,
so there is sufficient evidence to conclude that the proportion of voters who prefer the
Democratic candidate is equal to 74%.
The data suggest the population proportion is not significantly smaller than 74% at a = 0.01,
so there is not sufficient evidence to conclude that the proportion of voters who prefer the
Democratic candidate is smaller than 74%.
h. Interpret the p-value in the context of the study.
O If the population proportion of voters who prefer the Democratic candidate is 74% and if
another 79 voters are surveyed then there would be a 18.74% chance fewer than 70% of the 79
voters surveyed prefer the Democratic candidate.
O There is a 74% chance of a Type I error.
O If the sample proportion of voters who prefer the Democratic candidate is 70% and if another
79 voters are surveyed then there would be a 18.74% chance of concluding that fewer than 74%
of all voters surveyed prefer the Democratic candidate.
O There is a 18.74% chance that fewer than 74% of all voters prefer the Democratic candidate.
i. Interpret the level of significance in the context of the study.
O 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 71% and if
