You are conducting a study to see if the proportion of voters who prefer the Democratic candidate
is significantly larger than 58% at a level of significance of a = 0.05. According to your sample, 48 out
of 72 potential voters prefer the Democratic candidate.
a. For this study, we should use (Select an answer
b. The null and alternative hypotheses would be:
Но:
Select an answer
(please enter a decimal)
H1:
(Please enter a decimal)
Select an answer
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 (? v a
f. Based on this, we should Select an answer
the null hypothesis.
g. Thus, the final conclusion is that...
OThe data suggest the populaton proportion is significantly larger than 58% at a = 0.05,
so there is sufficient evidence to conclude that the proportion of voters who prefer the
Democratic candidate is larger than 58%
OThe data suggest the population proportion is not significantly larger than 58% at a =
0.05, so there is not sufficient evidence to conclude that the proportion of voters who
prefer the Democratic candidate is larger than 58%.
The data suggest the population proportion is not significantly larger than 58% at a =
0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer
the Democratic candidate is equal to 58%.
h. Interpret the p-value in the context of the study.
If the sample proportion of voters who prefer the Democratic candidate is 67% and if
another 72 voters are surveyed then there would be a 6.81% chance of concluding that
more than 58% of all voters surveyed prefer the Democratic candidate.
OThere is a 6.81% chance that more than 58% of all voters prefer the Democratic
candidate.
There is a 6.81% chance of a Type I error.
