Question

The confidence interval estimate is

mi/h<σ< mi/h.

(Round to one decimal place as needed.)

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
