A news article that you read stated that 57% of voters prefer the Democratic candidate. You think that the actual percent is different. 21 of the 35 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.01 level of significance? Use the classical approach. a. For this study, we should use z-test for a population proportion b. The null and alternative hypotheses would be: Ho: H₁: p # c. The test statistic z = d. The critical value = +/- ✓ or e. The test statistic is not or f. Based on this, we should fail to reject (please enter a decimal) (please show your answer to 3 decimal places.) V (Please enter a decimal) (Please show your answer to 3 decimal places.) in the rejection region. the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the population proportion is not significantly different 57% at a = 0.01, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different 57%. The data suggest the populaton proportion is significantly different 57% at a = 0.01, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different 57% The data suggest the population proportion is not significantly different 57% at a = 0.01, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 57%.

g. Thus, the final conclusion is that ...
The data suggest the population proportion is not significantly different 57% at a = 0.01, so
there is not sufficient evidence to conclude that the proportion of voters who prefer the
Democratic candidate is different 57%.
The data suggest the populaton proportion is significantly different 57% at a = 0.01, so there
is sufficient evidence to conclude that the proportion of voters who prefer the Democratic
candidate is different 57%
The data suggest the population proportion is not significantly different 57% at a = 0.01, so
there is sufficient evidence to conclude that the proportion of voters who prefer the
