You can put this solution on YOUR website! the average credit card debt for college seniors is 3262 if the debt is normally distributed with a standard deviation of 1100 find the probability that the senior owes between 2000 and 4000
-------------
z(2000) = (2000-3262)/1100 = -1.1473
z(4000) = (4000-3262)/1100 = 0.6709
----
P(2000< x <4000) = P(-1.1473< z <0.6709) = 0.6232 = 62.32%
