Find the indicated IQ score. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15.

96.25

Step-by-step explanation:

A ztable gives us values for P(X<x) and we're looking for P(X>x) so by the rule a symmetry we must make the value negative

Go to a ztable and find the value closest to .6 (I get .25), make this negative and let's set up our equation

-.25=(x-100)/15

solve for x

-3.75=x-100

x=96.25
