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

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

Q. 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

(i) $4 3^{rd}$ observation (ii) A.M. of $7 5^{th}$ and 76 th observation

(i) $4 3^{rd}$ observation (ii) $7 6^{th}$ observation

(i) can not be found (ii) can not be found

None of these

For the second set of observations
$N = 150$ (even), so median is the A.M. of $7 5^{th}$ and $7 6^{th}$ observation first set is not sorted so we have to arrange them in increasing or decreasing order

Q. 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

(i) 43rd observation (ii) A.M. of 75th and 76 th observation

(i) 43rd observation (ii) 76th observation
