Input Description
p0The expected sample proportion for 1.PropZTest. Must be
a
real number, such that 0 < p0 < 1.
xThe count of successes in the sample for the 1.PropZTest
and 1.PropZInt. Must be an integer ‚ 0.
nThe 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 c2.Test.
Xlist, Ylist The names of the lists containing the data for LinRegTTest.
Defaults are L1 and L2, 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.
