26. Researcher want to know if alcohol \emph{impairs} reaction time. They tested the reaction times of four participants. They then gave each participant alcoholic drinks, so that each participant had a BAC of 0.08. They then tested the reaction times of these participants again. The results in milliseconds were as follows: BAC = 0.0, Reaction time 1 BAC = 0.08. Reaction Time 2 Difference Abe 119 128 -9 Ben 125 165 -40 Cal 168 182 -14 Don 104 157 -53 Mean 129 158 -29 SD 27.46 22.55 20.99 Researcher want to know if alcohol impairs reaction time. What are the appropriate hypotheses for this test? H:HI - 42 = 0 HAM - M270 OHMI - 12 = 0 HA: MI-H2
