Input Description
p
0
The expected sample proportion for
1
.
PropZTest
. Must be
a
real number, such that 0 <
p
0
< 1.
x
The count of successes in the sample for the
1
.
PropZTest
and
1
.
PropZInt
. Must be an integer
‚
0.
n
The count of observations in the sample for the
1
.
PropZTest
and
1
.
PropZInt
. Must be an integer > 0.
x1
The count of successes from sample one for the
2
.
PropZTest
and
2
.
PropZInt
. Must be an integer
‚
0.
x2
The count of successes from sample two for the
2
.
PropZTest
and
2
.
PropZInt
. Must be an integer
‚
0.
n1
The count of observations in sample one for the
2
.
PropZTest
and
2
.
PropZInt
. Must be an integer > 0.
n2
The count of observations in sample two for the
2
.
PropZTest
and
2
.
PropZInt
. Must be an integer > 0.
C
.
Level
The confidence level for the interval instructions. Must be
‚
0 and <100. If it is
‚
1, it is assumed to be given as a
percent and is divided by 100. Default=0.95.
Observed (Matrix)
The matrix name that represents the columns and rows for
the observed values of a two-way table of counts for the
c
2
.
Test
.
Observed
must contain all integers
‚
0. Matrix
dimensions must be at least 2×2.
Expected (Matrix)
The matrix name that specifies where the expected values
should be stored.
Expected
is created upon successful
completion of the
c
2
.
Test
.
Xlist
,
Ylist
The names of the lists containing the data for
LinRegTTest
.
Defaults are
L
1
and
L
2
, respectively. The dimensions of
Xlist
and
Ylist
must be the same.
RegEQ
The prompt for the name of the
Y=
variable where the
calculated regression equation is to be stored. If a
Y=
variable is specified, that equation is automatically
selected (turned on). The default is to store the regression
equation to the
RegEQ
variable only.
