The weights of four randomly chosen bags of horse carrots, each bag labeled 20 pounds, were 20.3, 19.9, 20.5, and 20.0 pounds. Assume that the distribution of weights is Normal. Find a 95% confidence interval for the mean weight of all bags of horse carrots. 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. (Type integers or decimals rounded to the nearest hundredth as needed. Use ascending order.) O A. We are 95% confident the population mean weight is between and pounds. O B. We are 95% confident that the sample mean weight is between and pounds. O C. There is a 95% chance that all intervals will be between and pounds
