5. Confidence interval: A psychologist is studying "learning" in rats and wants to determine the overall time required for rats to learn to traverse a maze. She randomly selected 12 rats and found the times they took to be: 5.1, 1.6, 6.8, 2.3, 5.4, 1.8, 2.6, 6.2, 3.6, 3.4, 4.4, 4.8 a. Assuming this data is from a N(µ, σ) distribution where sigma is known to be 3.7, estimate the average time required for rats to learn to traverse this maze with a 90% confidence interval. Report 2 significant figures for the upper and lower bounds of the confidence interval. 5 Problem Set 3 ENVS 25 Spring 2024 b. How would you interpret this confidence interval in words? Make sure your explanation discusses what the interval says about the average time required for rats to learn to traverse the maze and includes both the bounds and the level of confidence. 612
