Hypothesis testing using t: One-sample We test if artificial sunlight during the winter months lowers one’s depression. Without the light, a depression test has m = 8. With the light, our sample with N = 41 produced M = 6. The t value = -1.83. What are the hypotheses? What is the critical value? What is the test statistic? What is the decision? State the conclusion.
