What does the width of a confidence interval tell us, and how does the size of a sample affect the width of a confidence interval for a population mean?
What will be an ideal response?
The narrower the interval, the better is our estimate of the population mean. As sample size increases, the interval width decreases. Increasing sample size reduces both the critical t value and the standard error of the mean in the formula for the confidence interval.
