About % of the area under the curve of the standard normal distribution is outside the interval z=[−1.42,1.42]z=[-1.42,1.42] (or beyond 1.42 standard deviations of the mean).

Expert Solution

P[Z<-1.42]= 0.0778.........by using Z table.

P[Z>1.42]

=1-0.9222...............by using Z table.

=0.0778

Therefore, the area under the curve of the standard normal distribution is outside = 0.0778+0.0778 =0.1556

0.1556 or 15.56%
