If \(\alpha \neq 0\) and the mean deviation of the observations \(\{k \alpha\}\), for \(k=1,2, \ldots \ldots, 50\) about its median is 50 , then \(|\alpha|=\)
- A 4
- B 3
- C 2
- D 5
Answer & Solution
Correct Answer
(A) 4
Step-by-step Solution
Detailed explanation
Given observations \(=\{\mathrm{K} \alpha\}\) Here, \(\mathrm{K}=1,2,3, \ldots \ldots, 50\) \[ \therefore \quad\{\mathrm{K} \alpha\}=\{\alpha, 2 \alpha, 3 \alpha, \ldots . ., 50 \alpha\} \] Number of observations \(=50\) (Even)…
