It was determined that the area to the left of a given t value will be
(1 − area to the right).
Use the table to find the area to the right of
t = 2.060
with 25 degrees of freedom.

According to the table, the area to the right of
t = 2.060
is
.
Now find the area to the left of
t = 2.060,
rounding the result to two decimal places.
(area to the left of t = 2.060) = 1 − (area to the right of t = 2.060)
= 1 −
=
Step 3
It was determined that the area to the left of a given t value will be (1 - area to the right)
Use the table to find the area to the right of t = 2.060 with 25 degrees of freedom.
