- Please see the second part below. I have included the answer from the first one. NBC News/Marist sampled 603 likely voters on 10-31-14. They found that 44% said they would vote for Michelle Nunn. We want to construct a 95% confidence interval to estimate the true proportion of likely voters who will vote for Nunn. What is the confidence interval? 0.4796 < p < 0.4004 0.5192 < p < 0.3608 0.3608 < p < 0.5192 0.4004 < p < 0.4796-------- THIS IS THE ANSWER. Interpret your confidence interval in context of the problem. A If many random samples of 603 voters were taken, 95% of the resulting confidence intervals would contain the value 44%. B We are 95% confident that the sample proportion of voters who will vote for Michelle Nunn is between 0.4004 and 0.4796. C We are 95% confident that 44% of voters will vote for Michelle Nunn. D We are 95% confident that the true percent of voters who will vote for Michelle Nunn is between 40.04% and 47.96%.

- Refer to diagram and apply to multiple choice.Indentify the t-score for a 95% confidence interval if the sample size is 50 t=Treating the 2015 Tobacco rate data as a sample, construct a 95% confidence interval for the mean tobacco rate for males and for females. Interpret each interval. Does it appear that males use tobacco at a higher rate than females? Justify your answer, using the confidence intervals in your explanation. Construct the same confidence interval for males at the 99% confidence level. Compare to the male 95% confidence interval from the previous question. What happened to the interval when the confidence level increased? Explain why.
