you are looking at around 81.5% i assume by shifting the standard deviation by the same amount on both sides the % will not change 
 i split the normal distribution curve into 8 pieces
.15 +2.35+13.5+34+34+13.5+2.35+.15    34+34+13.5=81.5%
the ones bolded are the sections that u r dealing with 
now the standard deviation is only 4400 so these numbers are going to be skewed off to the right a bit however bcus both sides are skewed evenly i believe they balance each other out 
im not completely certain of this but still i hope i helped if so give me a brainliest answer i need a few more to move up a rank   -J (:
