A researcher has found that pilots taking an over the counter antihistamine have poor reaction times. They performed an experiment on 44 pilots: 22 took the medication and 22 did not. Their reaction times to a command by Air Traffic Control was considered to be adequate or inadequate. Among those taking the medication, 13 were rated inadequate and 11 adequate.

Among those not-taking the medication, 9 were rated adequate and only 11 inadequate. Construct a contingency table. Run the Chi-Square test for independence using the calculator in the module. Note that StatCrunch does NOT support this type of Chi-Square.

State your findings and their significance.

	Taking Med	Not taking med
Reaction Adequate	11	9
Reaction Inadequate	13	11

What is the problem with this research study? Is the Chi-Square test appropriate? Why or why not? What could the researcher do to potentially rectify the problem?
