Detailed Solution & Explanation

We are given the observations: 27,30,26,44,42,51,37\displaystyle 27, 30, 26, 44, 42, 51, 37. 1. Arrange the observations in ascending order: 26,27,30,37,42,44,5126, 27, 30, 37, 42, 44, 51 Here, the number of observations is n=7\displaystyle n = 7 (which is odd). 2. The median is the n+12th\displaystyle \frac{n+1}{2}^{\text{th}} observation: Position of Median=7+12=4th observation\text{Position of Median} = \frac{7+1}{2} = 4^{\text{th}} \text{ observation} 3. The 4th\displaystyle 4^{\text{th}} observation in the ordered list is 37\displaystyle 37. Therefore, the median value is 37\displaystyle 37. Hence, **Option D** is the correct answer.
