Answer

Explanation:

Step1: Arrange data in ascending order

$71, 80, 105, 130, 131, 131, 178$

Step2: Find the middle - value

Since $n = 7$ (odd number of data points), the median is the $\left(\frac{n + 1}{2}\right)$-th value. $\frac{7+1}{2}=4$ - th value. The 4 - th value in the ordered list is $130$.

C. 130
