Question

Which of the following statements about interval estimates is NOT TRUE?

A. The interval estimate may or may not contain the value of the parameter being estimated

B. The confidence level of an interval estimate of a parameter is the probability that the interval estimate is equal to the point estimate

C. When the sample size is large, approximately 95% of the sample means fall within 1.96 standard deviations of the population means.

D. The formula for getting the interval estimate is equal to point estimate +, - the product of the critical value and standard error

E. Interval estimates are prefered over pont estimates since a confidence level can be specified

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.
