Intuitively, a standard deviation is a change from the expected value.
For the question you asked, this means that the change in the "results" doesn't exist, which doesn't really happen. If the standard deviation is 0, then it's impossible to perform the test! This shows that it's impossible to compute the probability with the "null" standard deviation from this form:
z = (x - µ)/σ
If σ = 0, then the probability doesn't exist.

What is the mean and standard deviation for the standard normal curve?

A standard normal distribution has a mean of and standard deviation of?
Mean 0, standard deviation 1.
Is the standard normal distribution has a mean of 1 and standard deviation of 0?
No.
What is true of a standard normal probability distribution aA mean of 0 and a standard deviation of 1 b A mean of 1 and any standard deviation of 1 c Any mean and a standard deviatio?
a is true.
What are the four numbers have the smallest possible standard deviation?
If all four numbers are the same, there is no standard deviation. The mean will be equal to all 4 numbers, resulting in a 0 standard deviation. Ex) 5,5,5,5
What is the mean and standard deviation for the standard normal curve?
Mean = 0 Standard Deviation = 1
A standard normal distribution has a mean of and standard deviation of?
Mean 0, standard deviation 1.
Is the standard normal distribution has a mean of 1 and standard deviation of 0?
No.
Why standard deviation scores over mean deviation as a more accurate measures of dispersion?
It is not. And that is because the mean deviation of ANY variable is 0 and you cannot divide by 0.
What is the distribution with a mean of 0 and a standard deviation of 1 called?
standard normal
What is standard deviation of 155.45?
The standard deviation is 0.
What is the standard deviation for 1.3?

a is true.
What would it mean if a standard deviation was calculated to equal 0?
A standard deviation of zero means that all the data points are the same value.
What does a standard deviation of 0 tell you?
The smaller the standard deviation, the closer together the data is. A standard deviation of 0 tells you that every number is the same.
If quartile deviation is 24. find mean deviation and standard deviation?
Information is not sufficient to find mean deviation and standard deviation.
What are the four numbers have the smallest possible standard deviation?
If all four numbers are the same, there is no standard deviation. The mean will be equal to all 4 numbers, resulting in a 0 standard deviation. Ex) 5,5,5,5
