Find the z-score having area 0.86 to its right under its standard normal curve?
Manthacl
This is the standard normal curve. To the left P(X<x) therefore to the right is P(X>x).
Therefore this means that to calculate the probability look up the Z score on the standard normal table. Then P(X>x) = 1-P(X<x).
This is because the curve is symmetrical arounds its mean.

Is the standard normal curve non symmetrical?
The standard normal curve is symmetrical.
What is the area under the standard normal curve?
the standard normal curve 2
He area under the standard normal curve is?
The area under the standard normal curve is 1.
What are the properties of a standard normal curve?
It is a normal curve with mean = 0 and variance = 1.
Normal curve is the meaning of standard normal distribution?
No, the normal curve is not the meaning of the Normal distribution: it is one way of representing it.
What is the difference between a general normal curve and a standard normal curve?
A standard normal distribution has a mean of zero and a standard deviation of 1. A normal distribution can have any real number as a mean and the standard deviation must be greater than zero.
Which normal distribution is also the standard normal curve?
The normal distribution would be a standard normal distribution if it had a mean of 0 and standard deviation of 1.
What is the standard deviation of the stardard normal curve?
1
Is normal curve symmetrical about its standard deviation?
nop its not
What is the mean and standard deviation for the standard normal curve?
Mean = 0 Standard Deviation = 1
What is the standard deviation of the normal IQ curve?
It is 15 points.
What must be done to a normal curve to make it into a standard normal distribution curve?
The mean must be 0 and the standard deviation must be 1. Use the formula: z = (x - mu)/sigma
