The axiom that states “sampling
distributions of means will tend
toward Normality when n is
large.”
What is the Central Limit
Theorem?
A single value that predicts the
value of the parameter.
What is a point estimate?
A range of values that attempts to
capture a parameter.
What is a confidence interval?
This is the lower end of the
confidence interval?
What is the lower confidence
limit?
Half of the confidence interval
length (quantifies precision).
What is the margin of error?
This is a test for which the
alternative hypothesis considers
values on both sides of the null.
What is the two-sided test?
This is what a statistician says
when the population standard
deviation for the variable comes
from a source outside the data.
What is “when σ is known”?
The test statistic used to conduct
a test of a mean when σ is
known.
What is a z statistic?
The probability distributions that
resemble Normal distributions
but with broader tails.
What are Student’s t
distributions?
Members of the t distribution
family are defined by this
parameter.
What are their degrees of
freedom ?
The test statistic used to test two
means when the population
standard deviation is not known.
What is a t statistic?
This is the upper end of the
confidence interval.
What is the upper confidence
limit?
The upper confidence limit
minus the lower confidence limit;
twice the margin of error.
What is the “confidence interval
length”?
The term that mean “the
probability of less or equal to a
given value.”
What is the cumulative
probability?
A value for a t random variable
that is greater than p × 100% of
the other t values.
What is a t percentile?
