A. 1.94
B. 2.02
C. 2.45
D. 2.57
A college football coach was interested in whether the college's strength
development class increased his players' maximum lift (in pounds) on the
bench press exercise. He asked six of his players to participate in a study.
The amount of weight they could each lift was recorded before they took the
strength development class. After completing the class, the amount of
weight they could each lift was again measured. The data are as follows:
Player
Weight before class
Weight after class

205
295

At the 5% level of significance, what is the critical value for testing whether
the strength development class increased the players' maximum lift?
Let to.05 1.94 (for 6 degrees of freedom),
to.05 2.02 (for 5 degrees of freedom),
to.025 2.45 (for 6 degrees of freedom),
to.025 -2.57 (for 5 degrees of freedom).
