π
0
Sets the assumed proportion of successes for the One-
proportion Z-test. From the Numeric view, set the value of
π
0
.
In a program, type:
 π
0
where 0 < π
0
< 1
Pooled Determine whether or not the samples are pooled for tests
or intervals using the Student’s T-distribution involving two
means. From the Numeric view, set the value of Pooled.
In a program, type:
0  Pooled—for not pooled (default).
1  Pooled—for pooled.
ProbList Contains the expected probabilities by category for the
chi-square goodness of fit test. In the Symbolic view, in the
Expected box, select Probability. Then, in Numeric
view, enter the data in ProbList.
s
1
Sets the sample standard deviation for a hypothesis test or
confidence interval. For a test or interval involving the
difference of two means or two proportions, sets the
sample standard deviation of the first sample. From the
Numeric view, set the value of s
1
.
In a program, type:
 s
1
s
2
For a test or interval involving the difference of two means
or two proportions, sets the sample standard deviation of
the second sample. From the Numeric view, set the value
of s
2
.
In a program, type:
 s
