The test will be conducted using the previous data.
1. Set to the list input (InputList) mode
Press
A
®
to input data 1 to list 2 (L2) and
data 2 to list 3 (L3).
2. After inputting lists, press
E

to open the
parameter input screen of “Ttest2samp”, then input
each parameter and test method.
*
When there is no Freq specification, calculation is
executed with weight as “1”.
*
Pooled is prediction for unknown
σ

.
Select “No” if
σ

,
σ
2
are subjectively unequal.
Select “Yes” if
σ

,
σ

are equal.
Calculation is executed using this prediction as the basis.
3. Press
Ï
to solve.
The answer is shown using two screens.
*
“df” indicates degree of freedom.
[05 TtestLinreg]
Tests the hypothesis of slope
β
of linear regression straight line “Y =
α
+
β
x” and
correlation coefficient
ρ
of two dimensional sample data obtained from two different
populations.
<Example 5>
The test is conducted under the assumption that the value of slope
β
and correlation
coefficient
ρ
obtained from statistical data X (65, 56, 78, 86, 92, 71, 68) and Y (95, 59,
88, 78, 75, 68, 80) randomly extracted from two different populations are
