The Upshot partnered with Siena College to conduct polls of dozens of the most competitive House and

Senate races across the country on 2018. They polled voters in New York's 22nd Congressional District. The poll was conducted from Nov. 1 to Nov. 4, 2018.

"We made 17,444 calls, and 500 people spoke to us. Our poll shows a close race. Of those polled, 46% say they will vote for Claudia Tenney while 45% say they will vote for Anthony Brindisi. The results from the poll had a margin of error of 4.7%".

1. What was the sample size and sample statistic(s)?

2. Use the estimate and margin of error from the poll to construct a range of values which the poll

suggests might contain the proportion of the population that favors Claudia Tenney. Then, construct a range of values that the poll suggests might contain the proportion of the population that favors Anthony Brindisi.

3. Interpret the confidence level of 95% for each interval.

4. Anthony Brindisi ended up winning the election for the New York's 22nd Congressional District with Brinidisi capturing 50.3% of the vote, and Tenney with 49.7% of the vote. Does the range of values for each candidate (from question 6) capture the actual percentages of voters for voted for each candidate? Explain your answers
