Systematic Sample
A.
A ____________________ assumes that each item or person in the population has an equal
chance of being included.
B.
The _____________________ states that if the sample size n is sufficiently large, the sampling
distribution of the means will be approximately normal no matter whether the population is
normally distributed, skewed, or uniform.
C.
___________________is a procedure based on sample evidence and probability theory to
decide whether the hypothesis is a reasonable statement.
D.
An ____________________ is a statement about a population parameter that is accepted when
the null hypothesis is rejected.
E.
The _____________________ is the risk we assume of rejecting the null hypothesis when it is
actually true.
F.
A ______________ is a value determined from sample information collected to test the null
hypothesis.
G.
The _________________ defines the location of all those values that are so large or so small
that the probability of their occurrence under a true null hypothesis is rather remote.
H.
If the null hypothesis is true and the researchers do not reject it, then a ______________ has
been made.
I.
For a _________________of hypothesis, the area of rejection is only in one tail of the curve.
J.
To conduct a __________________, the researcher must partition the
N
items in the
frame into
n
groups of k items where, k = N/n, rounding
k
to the nearest integer.
To
select a systematic sample, choose the first item to be selected at random from the
first
k
items in the frame.
Then select the remaining
n – 1
observations by taking
every
kth
item thereafter from the entire frame.
