Find the area under the standard normal distribution curve for each.
a. between z 0 and z 1.95
b. between z 0 and z 0.37
c. between z 1.32 and z 1.82
d. between z 1.05 and z 2.05
e. between z 0.03 and z 0.53 2. find

Respuesta :

From the standard normal tables, obtain
P(z<1.95) = 0.9744
P(z<0.37) = 0.6443
P(z<1.32) = 0.9066
P(z<1.82) = 0.9656
P(z<1.05) = 0.8531
P(z<2.05) = 0.9798
P(z<0.03) = 0.5120
P(z<0.53) = 0.7019
