find the area under the standard normal distribution curve b

find the area under the standard normal distribution curve between z = .15 and z = 1.15 .                 

15 is = .060

1.15 is = .375

Solution

HEre we have that area to the right of z= 0.15 is 0.60 and area to the left of z= 1.15 is given as 0.375

so required area under the curve between z= 0.15 and z= 1.15 is

=0.375 - 0.060 = 0.315

so required area is 0.315
