intervals, in 95 of the 100 results, the true point estimate would lie within the
given interval.
2) The range within which the true measure of effect lies with a stated probability,
or a certain degree of assurance (95%).
3) The confidence interval is calculated around the point estimate and quantifies the
variability around the point estimate.
4) The 1st and 2nd answers only
5) All of the above
