Answer:

use first median formula that is L+ (n/2-cf) / f ×h

Step-by-step explanation:

• use 90 as lower limit n means add frequency _ cf ( 5, then 5+15 ,20+20, 40+30,70+20,90+8)
• total frequency is equal to last number of cf
• 90+ (98/2 - 70)/98 × 9
• 90+(49 -70)/98 ×9
• 90+(21)/98×9
• 91.92 is the answer
