Question

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:

1. Based on what you now know about statistical inference, is Sara's conclusion a logical conclusion? Why or why not?

2. How many friend samples Sara should have in order to draw the conclusion with 95% confidence interval? Why?

3. How would you explain your conclusion to Sara without using any statistical jargon? Why?

Answer 1

For each part of the question illustrated below, solve them and provide the answers in a word document paper by showing the whole computation part. Assume that there are two candidates (that is, Jones and Johns) in the upcoming presidential election. Sara notes that she has described the presidential election candidates by 15 friends, and 10 stated that they are voting for the candidate Jones. Sara is thus convinced that candidate Jones will win the election as Jones gets more than 50% of votes. 1) Based on what you now know regarding statistical inference, is Sara's conclusion a logical conclusion? Explain why or why not? 2) Illustrate how many friend samples Sara must have in order to draw the conclusion by 95% confidence interval? Explain why? 3) Illustrate how would you describe your conclusion to Sara without employing any statistical jargon? Explain why?
