The length of a confidence interval changes when either the confidence level changes or the sample size changes. To illustrate this, imagine a statistician takes a sample from a population with a population standard deviation of 2. The sample mean is calculated to be 10. Construct 3 different confidence intervals: 3a) Assume the sample size is 30 and the confidence level is 95% 3b) Assume the sample size is 30 and the confidence level is 90% 3c) Assume the sample...
