ind the area under the standard normal curve to the left of z=−2.11 z=−2.11 and to the right of z=−0.42 z=−0.42 . Round your answer to four decimal places, if necessary.

Solutions

Expert Solution

P[Z<-2.11] = 0.0174.....................by using Z table.

P[Z>-0.42]  ................by using Z table.

Therefore, area to left of -2.11 and right of -0.42 = 0.0174 + 0.6628

=0.6802
