Suppose a certain species bird has an average weight of grams. We can assume that the weights of these birds have a normal distribution with grams. Find the sample size necessary for a 70% confidence level with a maximal error of estimate for the mean weights of the birds. Round your answer to the next higher whole number.

Suppose a certain species bird has an average weight of x=3.80 grams. Based on previous studies, we can assume that the weights of these birds have a normal distribution with o (the o has a little line coming out of it on the top, that is the symbol )= 0.37grams. For a small group of 10 birds, find the margin of error for a 70% confidence interval for the average weights of these birds. Select one: a. 0.06 grams b....
