1. Anne has a coin. She does not know if it is a fair coin. She flipped the coin 100 times and obtained 73 heads and 27 tails. She ran a computer simulation of 200 samples of 100 fair coin flips. The output of the proportion of heads is shown below. Samples = 200 Mean = 0.497 SD = 0.050 8 8 0.35 a. Calculate a 95% confidence interval for this simulation, and use it to determine whether Anne's coin is fair or unfair. b. What is the margin of error for this simulation?

Calculate, correct to the nearest tenth of a percent, the margin of error for this poll. 2b. If the candidate polled 3,000 likely voters instead of 900, what would the margin of error be? Round to the nearest tenth of a percent again
