269 armies have higher than 5600 goblin soldiers .
<u>Step-by-step explanation:</u>
Step 1: Sketch the curve.
The probability that X>5600 is equal to the blue area under the curve.
Step 2:
Since μ=5600 and σ=750 we have:
P ( X>5600 ) = P ( X−μ > 5600−5600 )=P ( X−μ/σ>5600−5600/750)
Since Z = x−μ/σ and 5600−5600/750=0 we have:
P ( X>5600 )=P ( Z>0 )
Step 3: Use the standard normal table to conclude that:
P (Z>0)=0.5
We have , 538 armies So , armies have higher than 5600 goblin soldiers is :
⇒
⇒
Therefore , 269 armies have higher than 5600 goblin soldiers .
