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. Remember to use the attached t-distribution chart when obtaining your critical region. Please answer the question using all of the steps: null in word, alternative in words, null in symbols, alternative in symbols, critical region t, df, all steps in the analysis computing your independent computed t, make a decision, and give a conclusion.
