A researcher wanted to know if individuals have better reaction times depending on when the test is taken -- in the morning or in the afternoon. He randomly assigned 16 participants to take the reaction time test in either the morning or the afternoon (8 for each condition). The following results were obtained, where lower scores indicate faster reaction time. The population Standard Deviation is known to be equal to 2. Conduct an appropriate statistical test using an alpha of .05. More information is given in the table than is needed. Morning Afternoon Difference Mean 81 78 4 Eight Steps of hypothesis testing 1.
