(2200 rev/min) x (360 deg/rev) x ( min/60 sec) = 13,200 degrees per second
(2200 rev/min) x (2 pi radians/rev) x (min / 60 sec) = <u>73 and 1/3 pi</u> radians/sec
A dependent means t-test determines if the differences between scores on the pretest and post-test measures differ significantly from Zero(0).
Benefits of pre-test measurements
This design is superior to the post-test-only control design because it adds pre-tests. Addition of pre-test: Improve your design ability to detect effects. You can investigate the impact of interventions on various sublevels of pretesting.
The design of the pre-test and post-test is similar to the in-subject experiment. In this experiment, each participant is first tested in control conditions and then in therapeutic conditions.

Notice the picture below
x = 1 and y = -1
now... recall your SOH CAH TOA
now.. what's the value for "r" or the radius? well, using the pythagorean theorem
Answer: A and C
Explanation: 6766 x 1/4 = 1,691.5, 6766 x 1/2 = 3383
Hope this helps
