using the unit normal table, find the proportion under the standard normal curve that lies to the right of the following values (round answers to four decimal places):

z= -1.35

z= -2.70

using the same table find the proportion under the standard normal curve that lies between the following values (round your answers to four decimal spaces)

the mean and z= 1.96

the mean and z=0

z= -1.40 and z=1.40

z= -.90 and z= -.70

z=1.00 and z= 2.00
