**Driving Exam Score Analysis Using Chebychev's Theorem**

The mean score on a driving exam for a group of driver's education students is 68 points, with a standard deviation of 5 points. Apply Chebychev's Theorem to the data using \( k = 2 \). Interpret the results.

**Chebychev's Theorem Application:**

1. **Mean (\( \mu \))**: 68 points
2. **Standard Deviation (\( \sigma \))**: 5 points
3. **\( k \) Value**: 2

**Interpretation:**

Chebychev's Theorem states that for any number \( k \) greater than 1, at least \( \left(1 - \frac{1}{k^2}\right) \times 100\% \) of the data values fall within \( k \) standard deviations of the mean.

Calculations for \( k = 2 \):
- Percentage: \( \left(1 - \frac{1}{2^2}\right) \times 100\% = 75\% \)

Range:
- Lower limit: \( \mu - k \sigma = 68 - 2(5) = 58 \)
- Upper limit: \( \mu + k \sigma = 68 + 2(5) = 78 \)

**Conclusion:**

At least 75% of the exam scores fall between 58 and 78. (Simplify your answers)
