Find p,
A) 22
B) 24
C) 21
D) 26
Correct Answer: A
Solution :
Given: No. of observations = 10 (even) Median = 25 We know that, for \[n=10\](even) Median = value of \[\frac{1}{2}\left[ {{\left( \frac{n}{2} \right)}^{th}}\text{item}+{{\left( \frac{n}{2}+1 \right)}^{th}}\text{item} \right]\] \[25=\,\text{Value}\,\text{of}\,\frac{1}{2}\left[ {{\left( \frac{10}{2} \right)}^{\text{th}}}\text{item}+{{\left( \frac{10}{2}+1 \right)}^{\text{th}}}\text{item} \right]\] \[25=V\text{alue}\,\text{of}\frac{1}{2}\left[ {{5}^{\text{th}}}\text{item+}\,{{\text{6}}^{\text{th}}}\text{item} \right]\] \[25=\frac{1}{2}\left[ x+2+x+4 \right]\Rightarrow x=22\]
