A veterinary researcher takes an SRS of 60 horses presenting with colic. The average age of the 60 burees with colic is 12 years. The average age of horses seen at the veterinary clinic was determined to be 10 years. The researcher also determined that the standard deviation of horses coning to the veterinary clinic is 8 years. The probability that a sample mean is 12 or larger for sample from the borse population is a. 0.0100 . b. 0.1264 . c. 0.0264 . d. 0.9736 . Type in a, b, c, d
