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.
