**Scores on an accounting exam ranged from 44 to 91, with quartiles \(Q_1 = 54.25\), \(Q_2 = 61.5\), and \(Q_3 = 79.25\).**

**(a) Select the correct box plot for the given data.**

- **Box Plot A**

  Description: Box Plot A shows a distribution with a median around 76. The interquartile range spans from approximately 58 to 85. The whiskers suggest a minimum close to 44 and an upper whisker reaching around 91.

- **Box Plot B**

  Description: Box Plot B exhibits a median around 61. The interquartile range extends from roughly 54 to 79. Whiskers indicate a lower value near 44 and an upper value near 91.

**(b) Describe its shape (skewed left, symmetric, skewed right).**

- ○ The distribution is symmetric.
- ○ The distribution is skewed left.
- ● The distribution is skewed right.

**Explanation:**

The box plot selected here (Box Plot B) indicates that the distribution of scores may be skewed right. This is inferred from the longer whisker on the left side and the concentration of the central box closer to the lower quartiles, suggesting that there are higher outliers influencing the distribution's shape.
