Question

find the area under the standard normal curve to the right z=
1

find the area under the standard normal curve to the left z=
1.25

find the value z(alfa) z0.04

Answer #1

1) The area to right of Z = 1.0

P( Z 1.0) using standard normal table

P( Z 1.0) = 1- P( Z < 1.0)

P( Z 1.0) = 1 - 0.8413

P( Z
1.0) = **0.1587**

2) P( Z 1.25) using standard normal table

P( Z
1.25) = **0.8944**

3) Z0.04 = **-1.75**

2. a) Find the area under the standard normal curve to the right
of z = 1.5.
b) Find the area under the standard normal curve to the left of
z = 1.
c) Find the area under the standard normal curve to the left of
z = -1.25.
d) Find the area under the standard normal curve between z = -1
and z = 2.
e) Find the area under the standard normal curve between z =
-1.5 and...

Find the indicated area under the standard normal curve.
To the left of z= -1.09 and to the right of z= 1.09
A) The total area to the left of z= −1.09 and to the right of z=
1.09 under the standard normal curve is:_______? (Round to four
deciamal places as needed).

1. Find the area under the standard normal curve to the left of
z = 1.66.
2. Find the area under the standard normal curve between z =
-1.75 and z = 0.96.
3. Find the z-score for which the area to its right is 0.67.
4. A normal population has mean 176=m and a standard deviation
.38=s What proportion of the population is more than 185?

Find the area under the standard normal curve between:
(a) P(-1.5<z<1.25)
(b) to the right of z=1.06
P(z<-2.58 or z>2.58)

Find the value of z if the area under a standard normal curve
(a) to the right of z is 0.3300 (b) to the left of z is .1112, (c)
between 0 and z, with z >0, is ,4803, and (d) between -z and z,
with z > 0, is .9250.

Find the value of z if the area under a standard normal curve
(a) to the right of z is 0.3974; (b) to the left of z is 0.0918;
(c) between 0 and z, with z > 0, is 0.4783; and (d) between -z
and z, with z > 0, is 0.9412
also i think you need to use the standard normal distribution
table.

a)Find the area under the standard normal curve between
z = -1.86 and z = 1.1, P(-1.86 <
z < 1.1). (Give your answer correct to four decimal
places.)
b)Find the area under the standard normal curve between
z = -2.53 and z = 1.4, P(-2.53 <
z < 1.4). (Give your answer correct to four decimal
places.)
c)Consider the normal curve. (Give your answers correct to four
decimal places.)
