A. which confidence interval is wider? The 95% confidence interval or the 99% confidence interval?

difference for both confidence intervals: 0.109

95% CI for difference: (-0.123, 0.340)

99% CI for difference: (-0.199, 0.416)

B. Given an arbitrary data set, is there a general relationship between confidence level and the width of the confidence interval? Explain.

Please make the answers to parts A and B detailed and easy to read and follow, thank you :)

Which of the following statements is true? The 95% confidence interval is wider than the 99% confidence interval. The ONLY way to reduce the width of a confidence interval is to reduce the confidence level. The required sample size for a population mean is ONLY dependent on population variance. Given population variance and sampling error, higher confidence level results in larger sample size.

Suppose you calculate a 95% confidence interval for the difference in population means. The confidence interval contains both negative and positive values. Will a 99% confidence interval based on the same data contain both negative and positive numbers as well? Choose the correct response from the options provided below. A. Yes. Keeping all other values the same, increasing the confidence level leads to a wider interval which would still include negative and positive numbers. B. No. Increasing the confidence level...

Sample mean is always: The lower endpoint of the 99% confidence interval. The middle of the confidence 99% interval. The upper endpoint of the 99% confidence interval. The average monthly electricity consumption in a random sample of 100 households in February 2016 in North Kingstown was 637 kilowatt hours (kWh) with sample standard deviation s=45kwh. A 95% confidence interval for the true electricity consumption in North Kingstown is 637 ± 1.95 * 45/10 637 ± 1.96 * 45 637 ±...

True or false?: 13) For a sample mean, the 99% confidence interval is wider than the 95% confidence interval. 14) The larger the sample size the more likely x̅ is close to μ. 15) Changing sample size has no effect on power when using the t test. 16) For the independent two-sample t test, increasing sample variances decreases power.

One can calculate the 95% confidence interval for the mean with the population standard deviation known. This will give us an upper and a lower confidence limit. What happens if we decide to calculate the 99% confidence interval? Describe how the increase in the confidence level has changed the width of the confidence interval. Do the same for the confidence interval set at 80%. Include an example with actual numerical values for the intervals in your post to help with...
