A study is performed to determine how alcoholaffects the brain's response to sound. Using appropriate control procedures, the researchers measure brain responses in 6 participants both beforeand after the participants drink an alcoholicbeverage.The results are as follows:

Participants No. 1,2,3,4,5,6

Before= 5.80, 5.88, 5.38, 5.40, 5.90, 5.71

After= 5.90, 6.05, 5.64, 5.58, 6.05, 5.87

Determine whether or not alcoholic ingestion affects brain response to sound.
