What level of confidence will produce a wider confidence interval -- 92% confidence or 97% confidence?
What level of confidence will produce a wider confidence interval -- 92% confidence or 97% confidence?
Homework Answers
A 97% confidence interval will be wider than a 92% confidence interval. A wider confidence interval implies a more accurate decision and to be more accurate (confident) that the true population value falls within the interval we will need to allow more potential values within the interval.For eg. -

At a confidence level of 95% a confidence interval for a population proportion is determined to be 0.65 to 0.75. If the sample size had been larger and the estimate of the population proportion the same, this 95% confidence interval estimate as compared to the first interval estimate would be Group of answer choices narrower. the same. wider.
