What is the use of confidence interval?
Can you give me an example of how it can be used?
Sure, let's say we want to estimate the average height of all 20-year-old males in the US. We take a random sample of 100 such males and use a 95% confidence interval to estimate the true population mean. The interval might be from 68 to 74 inches, which means we are reasonably confident that the true population mean height lies between those two values.
