Using the TI-84 calculator, find the area under the standard normal curve. Round the answers to four decimal places.
(a) Find the area under the standard normal curve that lies between z=-0.86 and z=1.82.
(b) Find the area under the standard normal curve that lies outside the interval between z=0.07 and z=2.31.
(c) Find the area under the standard normal curve to the left of z=1.02.
(d) Find the area under the standard normal curve to the right of z=1.17.
Part 1 of 4
The area between z=-0.86 and z=1.82 is 0.7707
Part 2 of 4
The area outside the interval between z=0.07 and z=2.31 is _______ .
b) Area under the standard normal curve that lies outside the interval between z = 0.07 and z = 2.31=
P(Z > 2.31) + P(Z < 0.07)
= 0.0468 + 0.5279
= 0.5747
c) The area to the left of z = 1.02 =
P(Z < 1.02) = 0.8461
d) The area to the right of z = 1.17 =
= P(Z > 1.17)
= 0.121
