- If n=14, (x-bar)=43, and s=16, construct a confidence interval at a 98% confidence level. Assume the data came from a normally distributed population. Give your answers to one decimal place. <μ<In each of Exercises, we have presented a confidence interval (CI) for the difference, µ1 - µ2, between two population means. Interpret each confidence interval. 99% CI is from -10 to 5.Suppose a certain species bird has an average weight of x = 3.2 grams. Based on previous studies we can assume that the weights of these birds have a normal distribution with sigma = 0.34 grams. For a small group of 18 birds , find a 98% confidence interval for the average weights of these birds. Write answer in interval notation with two decimal places.
