where
n1 Sets the size of the sample for a hypothesis test or
confidence interval. For a test or interval involving the
difference of two means or two proportions, sets the size
of the first sample. From the Numeric view, set the value of
n1.
In a program, type:
n1
n2 For a test or interval involving the difference of two means
or two proportions, sets the size of the second sample.
From the Numeric view, set the value of n2.

where
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.
s1 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 s1.
