(08.06 LC) Erin wants to know if warming up will help runners sprint faster. Twenty-six track and field athletes volunteered to participate in her study. She randomly assigns 13 athletes to warm-up for 10 minutes. All 26 participants sprint the same distance. She calculates the mean for each group and determines that the mean for the warm-up group was 10.9 seconds, and the mean for the other group was 12.9 seconds. To test the difference of means she re-randomized the data 54 times, and the differences are plotted in the dot plot below. What can Erin conclude from her study?

The cat Phillipa has become anxious. She has lost weight, and she is restless and sleepless. You are a veterinarian specializing in endocrinology. Your first determine that Phillipa has high thyroid hormone levels in her blood. Your next step is to determine whether the problem lies at the level of her hypothalamus, anterior pituitary, or thyroid gland.  Question: You discover an endocrine tumor in Phillipa’s hypothalamus. If this tumor is causing her symptoms, which hormone levels do you expect to find in her blood, compared to in a healthy cat? (Thyrotropin-releasing hormone = TRH, thyroid-stimulating hormone = TSH).
