Question 1039389
you would calculate the z-scores.
mean is 6500.
standard deviation is 750


the general formula is:
z = (x-m)/s
z is the z-score
x is the raw score
m is the mean
s is the standard deviation.


your low z-score would be:
z = (7225-6500)/750 = .966666666... which can be rounded to .97.


your high z-score would be:
z = (7670-6500)/750 = 1.56


look up the area to the left of the z-score of .97 and the z-score of 1.56 and subtract the smaller area from the larger area to get:


area between z-score of .97 and 1.56 = .9406 minus.8340 = .1066.


your closest solution is .1066 or 10.66% .
