Question

The ability of an interval estimate to contain the value of the population parameter is described by the


a. confidence level

b. degrees of freedom

c. precise value of the population mean (μ)

d. degrees of freedom minus 1

Answer 1

Answer: a. Confidence level

Explanation:

Interval estimation is the use of sample data to calculate an interval of possible (or probable) values of an unknown population parameter, in contrast to point estimation, which is a single number.

The confidence level shows that the interval estimate has the ability to contain the value of the population.parameter
