Using the standard normal (z) distribution table, what is the area
under the standard normal curve between 1.67 and 2.72?
a. 0.0442
b. 0.9525
c. 0.2563
d. 0.6140
The values of z-score are given.
A) Find the area under the normal curve to the right of
z = -0.84. Round the answer to four decimal places.
B) Find the area under the normal curve between
z = 0.43 and z = 1.33. Round the answer to four
decimal places.
C) Find the area under the normal curve between
z = -0.32 and z = 0.92. Round the answer to four
decimal places.
D) Find the area under the...
Find the area under the standard normal curve to the right of
the following z-values. Round your answer to four decimal
places.
(a) Find the area under the standard normal curve to the right
of =z0.51.
(b) Find the area under the standard normal curve to the right
of =z1.82.
(c) Find the area under the standard normal curve to the right
of =z2.46.
(d) Find the area under the standard normal curve to the right
of =z−2.35.
Using the z table (The Standard Normal Distribution Table), find
the critical value (or values) for the two-tailed test with
a=0.05
. Round to two decimal places, and enter the answers separated
by a comma if needed.
When do we use in probability:
-the area to the right of Z (when to use right Z-table)
-the area to the left (when to use left Z-table)
-and when do you subtract 1 from the area to the left instead of using the right table ?
