Real-World Examples: Applying the Confidence Interval Formula

Let's illustrate the Confidence Interval Calculator with examples. Assume a sample mean (x) of 50 and a standard deviation (y) of 5 for a sample size of 100. Using a 95% confidence level, the output would be a range around the mean where the true population parameter is likely to exist. Similarly, with an increased standard deviation, say 10, the range of the confidence interval would be wider, reflecting the greater variability in the data.
