Question

Given (i) $85$ observations which are not sorted and (ii) $150$ observations which are sorted and arranged in an increasing order. The median values of (i) & (ii) respectively can be found as

• A. (i) $43^{\text {rd }}$ observation (ii) A.M. of $75^{\text {th }}$ and 76 th observation
• B. (i) $43^{\text {rd }}$ observation (ii) $76^{\text {th }}$ observation
• C. (i) can not be found (ii) can not be found
• D. None of these

Answer 1

Answer: (D)

For the second set of observations
$N =150$ (even), so median is the A.M. of $75^{\text {th }}$ and $76^{\text {th }}$ observation first set is not sorted so we have to arrange them in increasing or decreasing order
