![You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is
significantly smaller than 70% at a level of significance of a = 0.01. According to your sample, 56 out of 84
potential voters prefer the Democratic candidate.
a. For this study, we should use z-test for a population proportion v
b. The null and alternative hypotheses would be:
Ho: ?v||Select an answer v
(please enter a decimal)
H1: ? v|Select an answer v
(Please enter a decimal)
c. The test statistic ?v =
(please show your answer to 3 decimal places.)
d. The p-value =
|(Please show your answer to 4 decimal places.)
e. The p-value is
f. Based on this, we should fail to reject
the null hypothesis.
g. Thus, the final conclusion is that ...
O The data suggest the population proportion is not significantly smaller than 70% at a = 0.01,
so there is sufficient evidence to conclude that the proportion of voters who prefer the
Democratic candidate is equal to 70%.
O The data suggest the population proportion is not significantly smaller than 70% 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 70%.
The data suggest the populaton proportion is significantly smaller than 70% at a = 0.01, so
there is sufficient evidence to conclude that the proportion of voters who prefer the
Democratic candidate is smaller than 70%](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0017d92f-fd5a-4a34-8e16-36b3a20e3d6d%2F7d9bf5c4-c5bb-4678-8add-a3717ac4ee13%2F97830i9_processed.png&w=3840&q=75)
