When people learn a new task, their performance usually improves when they are tested the next day, but only if they get 6 hours sleep (Sticckgold, et al., 2000). The following data demonstrate this phenomenon.  The participants learned a visual discrimination task on one day.  Half of the participants were allowed to have at least 6 hours of sleep and the other half were kept awake all night.

6 hours sleep
No sleep

                                           n =14                                                  n = 14

                                          M = 72                                                M =65

                                          SS = 932                                            SS = 706

Will the 6-hour sleep show a much higher performance rate? This time use a one-tail with alpha = .05    Show all of the steps.
