Extracted text: Suppose a certain species bird has an average weight of = 3.80 grams. Based on previous studies, we can assume that the weights of these birds have a normal distribution with o 0.37 grams. For a small group of 10 birds, find the margin of error for a 70% confidence interval for the average weights of these birds. Question 1 options: 0.02 grams 0.12 grams 0.06 grams 0.04 grams 1.04 grams
