Suppose that there are two
(2)
candidates
(i.e.,
Jones and Johns) in the upcoming
presidential
election. Sara
notes that she has discussed the presidential election candidates with
15
friends, and
10
said that they are voting for candidate
Jones. Sara is therefore convinced that
candidate Jones will win the election because Jones gets more than
50%
of votes.
Answer the following
questions in the space provided below:
Based on what you now know
about statistical inference, is Sara’s
conclusion a logical conclusion? Why or
why not?
First:
Use the Hypothesis test for proportion
Second:
Given the results of Sara’s poll,
determine the proportions for Jones
&
Johns.
Third:
Test for assumptions of normality
Fourth:
Determine your Confidence Level
Fifth:
Calculate the Z statistic
Sixth:
Determine whether you have enough evidence to reject the null
hypothesis. That
is, should Sara be confident that Jones
will win the presidential election based upon her poll
data.
