Refer to Exercise 48. A player with a batting average below 0.200 is at risk of sitting on the bench during important games. About what percent of players are at risk?

Exercise 48.

In baseball, a player’s batting average is the proportion of times the player gets a hit out of his total number of times at bat. The distribution of batting averages in a recent season for Major League Baseball players with at least 100 plate appearances can be modeled by a Normal distribution with mean μ = 0.261 and standard deviation σ=0.034 . Sketch the Normal density curve. Label the mean and the points that are 1, 2, and 3 standard deviations from the mean.
