The following questions is about histograms.
Which of the following would likely show a bimodal distribution in a histogram?
A)	The heights of all students in a high school band.
B)	The ages of students who attend a 4-year university.
C)	The number of hours preschoolers plays outside.
D)	The final exam grades for an introductory statistics course.


A bimodal distribution occurs when a dataset has two distinct peaks or modes. Let's analyze each option:

A) **The heights of all students in a high school band:**  
   This distribution is likely to be unimodal, with one peak centered around the average height of students. Since the students are generally of similar age and likely have a similar height range, it wouldn't be expected to have two distinct peaks.

B) **The ages of students who attend a 4-year university:**  
   University students generally fall into two groups: traditional students (ages 18-22) and non-traditional students (typically older, possibly in their late 20s or older). This could create two distinct peaks in the distribution, making it a bimodal distribution.

C) **The number of hours preschoolers play outside:**  
   The amount of time preschoolers play outside is likely to be centered around a common range, with most children playing outside for a similar number of hours. This would likely result in a unimodal distribution.

D) **The final exam grades for an introductory statistics course:**  
   Exam grades can vary, but they are more likely to form a single peak, depending on the difficulty of the exam and the students' preparedness. Although it could potentially have a bimodal distribution if there were two distinct groups (e.g., those who studied and those who didn't), this situation is less common.

**Correct Answer: B) The ages of students who attend a 4-year university.**
