A statistics instructor randomly selected four bags of oranges, each bag labeled 10 pounds, and weighed the bags. They weighed 9.5, 9.7, 9.6, and 9.8 pounds. Assume that the distribution of weights is Normal. Find a 95% confidence interval for the mean weight of all bags of oranges. Use technology for your calculations. Answer parts a and b below. a. Choose the correct interpretation of the confidence interval below and, if necessary, fill in the answer boxes to complete your choice. O A. We are 95% confident that the sample mean is between B. There is a 95% chance that all intervals will be between and and C. We are 95% confident the population mean is between and D. The requirements for constructing a confidence interval are not satisfied.
