Data Set 2: A pollster expects that roughly half the population individuals who are eligible to vote in 2020 actually voted. She polled 500 people and noted responses to the question "Did you vote or not?" A response of 'yes' was noted down as a '1' and a response of 'no' was noted down as a '0'. Write down an appropriate null and alternative hypothesis about the true proportion of people who voted after evaluating the summary of the data. What method can you use to test the hypothesis that you wrote down? What assumptions do you need to make to conduct the test? Construct an appropriate 95% confidence interval for the proportion of people who voted.
