99% confidence interval is wider than a 95% confidence interval. Because 95% confidence interval includes less of the sampling distribution as compared to the 99% confidence Interval. If the weather report on channel A said there was a chance that it would rain between 0 and 12 inches of rain tomorrow, but the weather report of channel B said there was a chance of 0.25 to 2 inches of rain tomorrow, which channel has a better chance of being correct?. So as the endpoints of your confidence interval stretch out, your confidence that the true parameter (μ-mean, p-proportion etc.) is within the confidence interval increases. For example, lets use 1000 simulations of the expected mortality rate in Country X. A 95% confidence interval might be between 3.2 and 5.6% and a 99% confidence interval might be between 3.8 and 5.2%. The size or width of a confidence Interval depends on three things, one of which is the confidence level. The bigger the confidence level, the wider the interval is. That's because a confidence level refers to the percentage of all possible samples that can be expected to include the true population parameter. Width of 99% confidence interval for population mean μ and with sample size (n) >30 is given as: C.I=x¯-2.576×σn, x¯+2.576×σn=x¯±2.576σn where, width is: 2.576σn 2.576 is the critical value at 0.99 confidence level or significance level (0.01) using standard normal table. σ is the standard deviation and n is the sample size.

State how you would respond to the following student posts in a discussion on how to interpret a 95% confidence interval for a population mean. One student posted their interpretation as “There is a 95% chance that this population mean will fall inside the confidence interval.” Another student responded to this post with “I don’t think that your interpretation is correct. The population mean is a fixed value. There is no chance involved. The population mean either falls inside the confidence interval or it does not.”

Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
A random sample of 40 12th-grade students was asked how long it took to get to school. The sample mean was 15.5 minutes and the sample standard deviation was 12.7 minutes. a. Find a 95% confidence interval for the population mean time it takes 12th-grade students to get to school. b. Would a 90% confidence interval based on this sample data be wider or narrower than the 95% confidence interval? Explain. Check your answer by constructing a 90% confidence interval and comparing the width of the interval with the width of the 95% confidence interval you found in part (a). a. The 95% confidence interval is from minutes to minutes. (Round to two decimal places as needed. Use ascending order.) b. Would a 90% confidence interval based on this sample be wider or narrower than the 95% confidence interval? O A. The 90% interval is wider because it has a lower confidence level, and therefore uses a smaller critical value, which creates a wider interval. O B. The 90% interval is wider because it…

Siblings Mary and David are each attempting to estimate the proportion of families in their neighborhood who have five or more children. Mary selects a random sample of 50 families to survey, and she observes a sample proportion of 0.10. David selects a random sample of 100 families to survey, and he also observes a sample proportion of 0.10. Mary and David each use their sample data to construct a 95% confidence interval. Who will have the more narrow confidence interval? A. Both intervals will have the same width since the sample proportions are the same. B. Both intervals will have the same width since the level of confidence is the same for each interval. C. Both intervals will have the same width since the sample proportions are the same and the level of confidence is the same for each interval. D. Mary's interval will be more narrow than David's interval. E. David's interval will be more narrow than Mary's interval.
