parameter

In statistical terms, a ________ of a
population is just a quantitative expression that
characterizes it

mean µ and the standard deviation σ

The two most common parameters:

estimates

The corresponding _________ are the sample
mean x and the sample standard deviation S.

confidence intervals

An effective way to express the uncertainty
associated with these estimates is to use _________

confidence interval

A _________ _________ designates the bounds within which a
parameter is expected to lie.

confident level, significance level

______ _______expresses the probability that the parameter does lie within a specified interval, where α is _______ ________

0.05

a 95% confidence level corresponds to α = _____

Normal Distribution

an arrangement of a data set in which most values cluster in the middle of the range and the rest taper off symmetrically toward either extreme
