1.) Use Table A to find the value z of a standard
Normal variable that satisfies each of the following conditions.
(Use the value of z from Table A that comes closest to
satisfying the condition.) In each case, sketch a standard Normal
curve with your value of z marked on the axis. (Round your
answers to two decimal places.)
(a) The point z with 64% of the observations falling
below it
z =
(b) The point...

1. Find the value z of a standard Normal variable
Z that satisfies each of the following conditions. (If you
use Table A, report the value of z that comes closest to
satisfying the condition.) In each case, sketch a standard Normal
curve with your value of z marked on the axis.
38% of the observations fall below z
70% of the observations fall above z
2.) Jorge scores 2090 on the SAT. Assuming that both tests
measure the same...

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

Use the table of standard normal probabilities (z table) to
answer the following questions. Please explain how you
calculate.
What is P(z >2.5)?
What is P(-0.8 < z < 1.5)?
What is P(0.65< z < 1.36)?
What z-value leaves 80 % of the normal distribution to its
right?
What z-value, and its negative, leaves 10 % of the normal
distribution in each tail (a total of 20% of the distribution in
both tails combined)?

Using the unit normal table, find the proportion under the
standard normal curve that lies between the following values.
