In a study which compares reaction times between two groups, one which has been asked to run a treadmill for 15 minutes and one not using the treadmill,
-8) In the above reaction time study, a difference between two groups in favour of the treadmill condition where p is less than .05 would indicate:
A) Proof that running a treadmill reduces reaction times
B) Support for the null hypothesis
C) Support for the proposal that running a treadmill reduces reaction times
D) That the alternative hypothesis should be rejected

A p-value less than .05 typically indicates statistical significance, suggesting evidence against the null hypothesis and in support of the alternative hypothesis, which in this context is that running on a treadmill reduces reaction times. It does not prove causality but supports the proposal.
