Question

Use Minitab Express to construct a standard normal distribution to find the proportion of the curve above z = 2. Show your distribution

Answer #1

Steps to follow while using Minitab Express

Open Menu

Graph>Probability Distribution Plots>View probabilty

New box with two options appear

(a)Distribution>Normal

Mean =0.0

Standard deviation = 1.0

(b)Shaded Area>right tailed

x-value = 2

Given Graph showing distribution appears in result, where propotion above z=2 is 2.275%

You can cross check this value using Excel formula =1-NORM.S.DIST(2,TRUE)

Standard normal proportion. Use table B to find the proportion
of a standard normal distribution that is: (a) below -1.42 (b)
above 1.42 (c) below 1.25 (d) between 1.42 and 1.25

1.For a standard normal distribution, find:
P(z < -2.22)
Express the probability as a decimal rounded to 4 decimal
places.
2.For a standard normal distribution, find:
P(z > -1.29)
Express the probability as a decimal rounded to 4 decimal
places.
3. For a standard normal distribution, find:
P(-2.56 < z < -2.43)
4.For a standard normal distribution, find:
P(z < c) = 0.3732
Find c rounded to two decimal places.

Use Table A to find
the proportion of the standard Normal distribution that satisfies
each of the following statements.
(a)z<0.22(b)z>0.22(c)z>0.0999999999999996(d)0.0999999999999996<z<0.22(a)z<0.22(b)z>0.22(c)z>0.0999999999999996(d)0.0999999999999996<z<0.22

Using the unit normal table, find the proportion under the
standard normal curve that lies between the following values.
(Round your answers to four decimal places.)
(a) the mean and z = 0 (b) the mean and z = 1.96 (c) z = −1.80
and z = 1.80 (d) z = −0.80 and z = −0.20 (e) z = 1.00 and z =
2.00

Using the unit normal table, find the proportion under the
standard normal curve that lies between the following values.
(Round your answers to four decimal places.) (a) the mean and z = 0
0.3989 Incorrect: Your answer is incorrect. (b) the mean and z =
1.96 0.0250 Incorrect: Your answer is incorrect. (c) z = −1.30 and
z = 1.30 (d) z = −0.80 and z = −0.20

a.) For a standard normal curve, find the area between z = 0.28
and z = 1.95. (Use 4 decimal places.)
b.) Find the positive z value such that 89% of the
standard normal curve lies between –z and z. (Use
2 decimal places.)
c.) Given a normal distribution with population standard
deviation of 21 and a mean of μ = 29. If a random sample
of size 62 is drawn, find P(29 ≤ x ≤ 31).

About % of the area under the curve of the standard normal
distribution is outside the interval Z = (-0.77,0.77) (or beyond
0.77 standard deviations of the mean). Please show your answer to 2
decimal places show on how to imnput on graphing calculator

Assume a standard Normal distribution. Draw a well-labeled
Normal curve for each part.
a. Find the z-score that gives a left area of 0.7303
b. Find the z-score that gives a left area of 0.1647

1. About ____ % of the area under the curve of the standard
normal distribution is between z = − 1.863 z = - 1.863 and z =
1.863 z = 1.863 (or within 1.863 standard deviations of the
mean).
2. About ____ % of the area under the curve of the standard
normal distribution is outside the interval
z=[−2.24,2.24]z=[-2.24,2.24] (or beyond 2.24 standard deviations of
the mean).
3. About ____ % of the area under the curve of the...
