Question

Quizplus · Accepted Answer

Estimating population means is typically done using confidence intervals. Confidence intervals provide a range of values within which we expect the population mean to fall with a certain level of confidence. This approach can be more informative than hypothesis testing, as it provides a range of plausible values for the population mean rather than a simple yes/no answer about whether the null hypothesis can be rejected.
