Cattle The Virginia Cooperative Extension reports that the mean weight of yearling Angus steers is 1152 pounds. Suppose that weights of all such animals can be described by a Normal model with a standard deviation of 84 pounds. a) How many standard deviations from the mean would a steer weighing 1000 pounds be? b) Which would be more unusual, a steer weighing 1000 pounds or one weighing 1250 pounds?

ST 701: Week 1 Notes MaLyn Lawhorn August 17, 2017 Probability Theoretical Basics ▯ In the words of Bruno de Finetti, ”Probability does not exist!” ▯ This means that probability is an idea that is relative to individuals beliefs, available infor- mation, etc. ▯ Therefore, it is possible when two people conduct two separate experiments about the same probability, they can get different answers. ▯ Probabilities, then, can be manipulated fairly easily but not as easily evaluated.
