Matijczak et al. (2023) was curious: Does interacting with a dog have an effect on anxiety for adults? To study their research question, researchers used a sample of N = 90 adults. After a stress-inducing activity, the sample interacted with a dog for a short period of time. Then, the sample completed the State/Trait Anxiety Inventory (STAI) and had M = 48. For the general population of adults who did not interact with a dog, scores on the STAl form a normal distribution with u = 52, o = 15. On the STAl, the higher the score, the more anxiety an individual has. Based on Research Study #1 provided above, answer the following question: 1. Based on the information provided, which one of the following statistical tests should you use? What hypothesis test? hypothesis test with sample score (X) hypothesis test with population mean (p) hypothesis test with sample mean (M), also called the z Test
