A news article that you read stated that 56% of voters prefer the Democratic candidate. You think
that the actual percent is larger. 122 of the 214 voters that you surveyed said that they prefer the
Democratic candidate. What can be concluded at the 0.01 level of significance?
a. For this study, we should use z-test for a population proportion v
b. The null and alternative hypotheses would be:
Ho: ? vSelect an answerV
(please enter a decimal)
H.:? v Select an answer v
(Please enter a decimal)
c. The test statistic ?v =
(please show your answer to 4 decimal places.)
d. The p-value =
e. The p-value is >v a
f. Based on this, we should fail to reject
g. Thus, the final conclusion is that ..
(Please show your answer to 4 decimal places.)
vv the null hypothesis.
O The data suggest the population proportion is not significantly larger 56% at a = 0.01, so
there is not sufficient evidence to conclude that the proportion of voters who prefer the
Democratic candidate is larger 56%.
O The data suggest the population proportion is not significantly larger 56% at a = 0.01, so
there is sufficient evidence to conclude that the proportion of voters who prefer the
Democratic candidate is equal to 56%.
O The data suggest the populaton proportion is significantly larger 56% at a = 0.01, so
there is sufficient evidence to conclude that the proportion of voters who prefer the
Democratic candidate is larger 56%
h. Interpret the p-value in the context of the study.
O If the population proportion of voters who prefer the Democratic candidate is 56% and if
another 214 voters are surveyed then there would be a 38.31% chance that more than
57% of the 214 voters surveyed prefer the Democratic candidate.
O There is a 38.31% chance of a Type I error.
