Question

compare the 95% and 99% confidence intervals for the hours of sleep a student gets. in at least 2 sentences, explain the difference between these intervals and why this difference occurs.

Answer 1

The 99% confidence interval will be wider than the 95% confidence interval because it encompasses a greater range of possible values, meaning that there is a lower chance of the true population parameter falling outside the interval. The 95% confidence interval means that if the study was repeated many times, 95% of the intervals constructed would contain the true population parameter, whereas the 99% confidence interval means that 99% of the intervals constructed would contain the true population parameter.
