Question 1207905: 1. To test the effect of alcohol in increasing the reaction time to respond to a given stimulus, the reaction times of seven people were measured. After consuming 89 mL of 40% alcohol, the reaction time for each of the seven people was measured again. Do the following data indicate that the mean reaction time after consuming alcohol was greater than the mean reaction time before consuming alcohol? Use 𝛼 = 0.05. (Use 𝜇before − 𝜇after = 𝜇d. Round your answers to three decimal places.)
DATA:-
Person____1____2____3____4____5____6____7 (Ignore the lines - represents space)
Before____5____6____5____5____3____6____1 (Ignore the lines - represents space)
After_____7____8____3____6____3____4____6 (Ignore the lines - represents space)
Test statistic: t =
Rejection region: If the test is one-tailed, enter NONE for the unused region.
t > _______
t < _______
You can put this solution on YOUR website! This is a 1-way paired t=test with df=6
t>1.943 is the critical value for the rejection region, since expect reaction time to be greater.
