You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is
significantly different from 62% at a level of significance of a = 0.05. According to your sample, 27 out of
50 potential voters prefer the Democratic candidate.
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Select an answer v
Ho: ?
H₁: ?
Select an answer ✓
c. The test statistic ? =
d. The p-value=
e. The p-value is ? a
f. Based on this, we should Select an answer the null hypothesis.
g. Thus, the final conclusion is that ...

The data suggest the populaton proportion is significantly different from 62% at a = 0.05, so
there is sufficient evidence to conclude that the proportion of voters who prefer the
Democratic candidate is different from 62%
O The data suggest the population proportion is not significantly different from 62% at a = 0.05,
so there is sufficient evidence to conclude that the proportion of voters who prefer the
Democratic candidate is equal to 62%.

prefer the Democratic candidate.
