Answer 1

As the percentage of particular intervention required for 3419 acute stroke survivours is given .from this data we can calculate.

•Total number of patient undergoing particular intervention according to given data= 3419×(percentage given÷100).

•Observed number of patient undergoing surgical intervention=X

•overmet or undermet =X - { 3419×(percentage given÷100) }

Total no. of paliant gehtning lhrombolytic Therapy = 3419 x 16 = 376.09 observed no. of palient undergone thrombolylie Therapy As the actual number or observed is lower han given dala or expected. Therefore it is an undermel. .. undermelo . 376.09 - 52324.09 of their is figures after point. Then we can round off, if needed. observed no. of palisand andergone sugary I 196 As the actual number or observed number is greaker it is an overmet overmet 196 - 136.76 = 59.24

* rest of the questions can be calculated using same equation.
