Why is the standard normal probability distribution unique?
a mean of 1 and any standard deviation
Suppose z has a standard normal distribution with a mean of 0 and a standard deviation of 1. the probability that z is less than 1.15 is?
probability is 43.3%
How much is 84 percentile equals mean plus 1 standard deviation or mean plus 1.4 standard deviation. Can you give me reference also please?
The cumulative probability up to the mean plus 1 standard deviation for a Normal distribution - not any distribution - is 84%. The reference is any table (or on-line version) of z-scores for the standard normal distribution.
Why does a Uniform distribution have a greater standard deviation?
The answer depends on greater standard deviation that WHAT!
A standard normal distribution has a mean of and standard deviation of?
Mean 0, standard deviation 1.
Is the uniform probability distribution's standard deviation proportional to the distribution's range?
no
What is Normal of probability distribution?
with mean and standard deviation . Once standardized, , the test statistic follows Standard Normal Probability Distribution.
What is Normal of Standard Normal Probability Distribution?
with mean of and standard deviation of 1.
Why is the standard normal probability distribution unique?
a mean of 1 and any standard deviation
How do you calculate probability given mean and standard deviation?
The mean and standard deviation do not, by themselves, provide enough information to calculate probability. You also need to know the distribution of the variable in question.
What is the standard deviation of a standard normal distribution?
The standard deviation in a standard normal distribution is 1.
Suppose z has a standard normal distribution with a mean of 0 and a standard deviation of 1. the probability that z is less than 1.15 is?
probability is 43.3%
In the standard normal distribution the standard deviation is always what?
The standard deviation in a standard normal distribution is 1.
How much is 84 percentile equals mean plus 1 standard deviation or mean plus 1.4 standard deviation. Can you give me reference also please?
The cumulative probability up to the mean plus 1 standard deviation for a Normal distribution - not any distribution - is 84%. The reference is any table (or on-line version) of z-scores for the standard normal distribution.
Is probability density function and gaussian distribution function are same?
yes, h=1/sigma(standard deviation)
What information do you need to calculate a probability with a normal distribution?
Only the mean, because a normal distribution has a standard deviation equal to the square root of the mean.
If normal distribution is between 110 and 190 how can I find the probability that it will be between 135 and 165?
You need to know the standard deviation or standard error to answer the question.
