Exercise  Testing the Reaction Time of a PersonThe reaction time of a person is of much importance in many critical situations. It is also wellknown that the reaction time is strongly influenced by the consumption of alcohol or by the degree of fatigue. In order to decide whether the reaction time of a person is above some predefined threshold, a onesample ttest should be applied. In order find significant differences for different experimental setups, a twosample ttest should be used. 9 persons have repeated a reaction test on two different occasions between
10 and 40 times. The first test run was performed in early afternoon at
the beginning of a twohour course in statistics (column denoted by "tearly").
The second series of tests were conducted after the twohour course ("tlate").
