Exercise 1.4 (5pts). A farmer recorded the weights of 25 randomly selected pigs from his farm. A 95% confidence interval for the mean weight was calculated to be from 280.2 to 289.8 pounds. What is being estimated by this confidence interval? Choose one: a. the weights of all pigs at this farm. b. the mean weight of 25 pigs at this farm. c. the mean weight of all pigs at this farm. d. the middle 95% of weights for pigs at this farm.
