In a Study on the Influence of Exercise Type on Pulse

Multiple Choice

In a study on the influence of exercise type on pulse rate and dependence on dietary preference, the following table details Tests of Between-Subjects Effects. The following output is produced for diet x intensity
Multivariate tests of significance (S = 1, M = 0, N = 701/2)
The reported findings are written as follows
F(1, 143) = 20.82, p = .000
What do you deduce by this result?

A) Change in pulse rate is not affected by dietary preference.
B) There is no difference in pulse rate in relation to intensity levels.
C) Change in pulse rate across intensity levels depends on dietary preference.
D) None of the above.
