# Understanding the Distribution of Fly Ball Distances in Baseball

## Overview

Suppose that the distance of fly balls hit to the outfield in baseball is normally distributed with a mean of 234 feet and a standard deviation of 54 feet. We randomly sample 49 fly balls to analyze their distribution.

### Part (a)

**Objective:** Determine the distribution of the average distance (in feet) for 49 fly balls.

Given:
- Mean (μ) = 234 feet
- Standard deviation (σ) = 54 feet
- Sample size (n) = 49

The distribution of the sample mean \( \bar{X} \) is normally distributed with:
- Mean = μ
- Standard deviation = \( \frac{σ}{\sqrt{n}} \)

Calculate and round the standard deviation to two decimal places.

### Part (b)

**Objective:** Calculate the probability that the 49 fly balls traveled an average of less than 226 feet.

- Find \( P(\bar{X} < 226) \).
- Round your answer to four decimal places.

**Graphical Representation:**
- Four normal distribution graphs are presented.
- The graph with the correct shaded area corresponds to the lower tail of the normal distribution up to 226 feet.

### Part (c)

**Objective:** Find the 80th percentile of the distribution of the average distance of 49 fly balls.

- Calculate the value corresponding to the 80th percentile.
- Round your answer to two decimal places.

These exercises help in understanding the application of normal distribution concepts and how to calculate probabilities and percentiles from a sample.
