On January 1, 2011, a new standard for baseball bat liveliness called BBCOR (Ball-Bat Coef-cient of Restitution)

Question:

On January 1, 2011, a new standard for baseball bat "liveliness" called BBCOR (Ball-Bat Coef-cient of Restitution) was adopted for teams playing under NCAA rules. A higher BBCOR allows the ball to travel farther when hit, so bat manufacturers want a high BBCOR. The maximum allowable BBCOR is 0.500. BigBash Inc. produces bats whose BBCOR is N(0.480,0.008). What percentage of their bats will exceed the BBCOR standard?
