2
The axiom that states sampling distributions of
means will tend toward Normality when n is large.
3
What is the Central Limit Theorem?
4
A single value that predicts the value of the
parameter.
5
What is a point estimate?
6
A range of values that attempts to capture a
parameter.
7
What is a confidence interval?
8
This is the lower end of the confidence interval?
9
What is the lower confidence limit?
10
Half of the confidence interval length
(quantifies precision).
11
What is the margin of error?
12
This is a test for which the alternative
hypothesis considers values on both sides of the
null.
13
What is the two-sided test?
14
This is what a statistician says when the
population standard deviation for the variable
comes from a source outside the data.
15
What is when s is known?
16
The test statistic used to conduct a test of a
mean when s is known.
17
What is a z statistic?
18
The probability distributions that resemble
Normal distributions but with broader tails.
19
What are Students t distributions?
20
Members of the t distribution family are defined
by this parameter.
21
What are their degrees of freedom ?
22
The test statistic used to test two means when
the population standard deviation is not known.
23
What is a t statistic?
24
This is the upper end of the confidence interval.
25
What is the upper confidence limit?
26
The upper confidence limit minus the lower
confidence limit twice the margin of error.
27
What is the confidence interval length?
28
The term that mean the probability of less or
equal to a given value.
29
What is the cumulative probability?
30
A value for a t random variable that is greater
than p 100 of the other t values.
31
What is a t percentile?
