Example To calculate the 2-Sample t Interval when two lists of data are
input
For this example, we will obtain the 2-Sample t Interval for data 1
= {55, 54, 51, 55, 53, 53, 54, 53} and data 2 = {55.5, 52.3, 51.8, 57.2,
56.5} without pooling when C-Level = 0.95.

Left ................. interval lower limit (left edge)
Right ............... interval upper limit (right edge)
df .................... degrees of freedom
o1 .................... sample 1 mean
o2 .................... sample 2 mean
x1 σ n-1 ............... sample 1 standard deviation
x2 σ n-1 ............... sample 2 standard deviation
n1 .................... sample 1 size
n2 .................... sample 2 size
The following item is also shown when Pooled = On.
xp σ n-1 ............... pooled sample standard deviation
Confidence Interval 18 - 7
