1.A sports psychologist read that lack of sleep impairs reaction time and wants to replicate the study. She collected data on two samples. Group 1 was kept awake for 24 hours. Group 2 was allowed to sleep comfortably for 8 hours. The following morning, both groups were given a test of reaction time with the following results shown below. Does sleep deprivation have an adverse effect on reaction time? Use = 0.05.

Group 1:= 51

S₁= 5.02

n₁ = 14

Group 2:= 46

S₂= 6.43

n₂ = 11
