the following histogram shows the age of each person on a hiking trail. in which interval is the median age…

Explanation:

Step1: Calculate total number of hikers

$4 + 2+2 + 1+2=11$

Step2: Determine position of median

Since $n = 11$ (odd - numbered data set), the median is the $\left(\frac{n + 1}{2}\right)$-th value. $\frac{11+ 1}{2}=6$-th value.

Step3: Find the interval of the median

Count the frequencies from the first interval. The first interval ($0 - 5$) has $4$ hikers. The second interval ($5 - 10$) has $2$ hikers. $4+2 = 6$. So the median lies in the $5 - 10$ interval.

Answer:

B. 5 to 10
