Textbook Question
Chapter 6, Problem 16P
In 2014 the New York Yankee had a team batting average of μ – 245 (actually 0.245 but we will avoid the decimals). Of course, the balling avenge varies from game to game, but assuming that the distribution of batting averages for 162 games is normal with a standard deviation of σ = 40 points, answer each of the following.
- a. If you randomly select one game from 2014, what is the
probability that the team balling average was over 300? - b. If you randomly select one game from 2014, what is the probability that the team batting average was under 200?
