- True or False. Confidence intervals are useful because they provide you with a range of values into which you can be certain that Mu falls.
Homework Answers
False
We are not certain that the value of mean will be contained within the confidence interval. We only have a certain amount of confidence that the interval may contain the actual value of mu.

For example, A Researcher is using the confidence Interval range values that have the true value of the population mean so the variable that would be probably more useful in this particular work in other to create an interval with 95% of 60-75-year-old patients point of estimate falls under systolic blood pressure within the mean of 134 mmHg for 10 patients.
