Introduction

In the game of baseball, fly balls are an essential part of the game, and understanding the distribution of their distances can provide valuable insights for players, coaches, and fans alike. In this article, we will explore the distribution of fly ball distances, assuming that they follow a normal distribution with a mean of 270 feet and a standard deviation of 41 feet.

The Normal Distribution

The normal distribution, also known as the Gaussian distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean. In the context of fly ball distances, the normal distribution can be represented by the following probability density function:

f(x) = (1/σ√(2π)) * e^(-((x-μ)2)/(2σ^2))

where x is the distance in feet, μ is the mean (270 feet), σ is the standard deviation (41 feet), and e is the base of the natural logarithm.

Calculating the Distribution of Fly Ball Distances

To calculate the distribution of fly ball distances, we need to find the probability that a fly ball will be hit within a certain distance range. Let's consider the following scenarios:

Scenario 1: Fly Ball Distance within 200-300 Feet

To find the probability that a fly ball will be hit within 200-300 feet, we need to calculate the z-scores for the lower and upper bounds of the range.

z = (x - μ) / σ

For x = 200 feet:

z = (200 - 270) / 41 z = -70 / 41 z = -1.71

For x = 300 feet:

z = (300 - 270) / 41 z = 30 / 41 z = 0.73

Using a standard normal distribution table or calculator, we can find the probabilities corresponding to these z-scores:

P(X < 200) = P(Z < -1.71) = 0.0434 P(X < 300) = P(Z < 0.73) = 0.7674

The probability that a fly ball will be hit within 200-300 feet is:

P(200 < X < 300) = P(X < 300) - P(X < 200) = 0.7674 - 0.0434 = 0.7240

Scenario 2: Fly Ball Distance within 250-350 Feet

To find the probability that a fly ball will be hit within 250-350 feet, we need to calculate the z-scores for the lower and upper bounds of the range.

For x = 250 feet:

z = (250 - 270) / 41 z = -20 / 41 z = -0.49

For x = 350 feet:

z = (350 - 270) / 41 z = 80 / 41 z = 1.95

Using a standard normal distribution table or calculator, we can find the probabilities corresponding to these z-scores:

P(X < 250) = P(Z < -0.49) = 0.3121 P(X < 350) = P(Z < 1.95) = 0.9734

The probability that a fly ball will be hit within 250-350 feet is:

P(250 < X < 350) = P(X < 350) - P(X < 250) = 0.9734 - 0.3121 = 0.6613

Conclusion

In this article, we explored the distribution of fly ball distances in baseball, assuming that they follow a normal distribution with a mean of 270 feet and a standard deviation of 41 feet. We calculated the probabilities of fly balls being hit within certain distance ranges, demonstrating the application of the normal distribution in real-world scenarios. The results provide valuable insights for players, coaches, and fans, highlighting the importance of understanding the distribution of fly ball distances in the game of baseball.
