Question

Whenever the population standard deviation is known and the population has a normal or near-normal distribution, which distribution is used in developing interval estimation?

a. alpha distribution

b. t distribution

c. non-standard distribution

d. z distribution (standard normal distribution)

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.
