∙ 12y agoProportion of scores between -2 and 1 in a normal distribution is φ(1)-φ(-2) = .8413-.0228 = .8185.
.8185 = 81.85 %
Here φ(t) = P(x ≤ t)

What is the difference between a normal distribution and the standard normal distribution?
The standard normal distribution is a normal distribution with mean 0 and variance 1.
What percentage of a normal distribution is located in the tail beyond a z-score of z - 1.20?
11.51% of the distribution.
What is the Difference between normal and gaussian distribution?
Actually the normal distribution is the sub form of Gaussian distribution.Gaussian distribution have 2 parameters, mean and variance.When there is zero mean and unit variance the Gaussian distribution becomes normal other wise it is pronounced as Gaussian.Wrong! The standard normal distribution has mean 0 and variance 1, but a normal distribution is the same as the Gaussiand, and can have any mean and variance.

What percentage of the data in a normal distribution is represented by 1 SD of a sample?
Assuming that we have a Normal Distribution of Data, approx. 65% of the data will fall within One Sigma.
What percentage of a normal distribution is located in the tail beyond z equals 2.00?
2.27%
What percentage of the area of a normal standard distribution falls between z and z?
Zero.
What percentage of scores fall between 0 and -2 in a normal distribution?
2
What percentage of the area of a normal standard distribution falls between z1 and z -1?
2
Percentage between 415 and 515 standard deviation 100 and mean is 515?
34.1% with the normal distribution.
What is the difference between a normal distribution and the standard normal distribution?
The standard normal distribution is a normal distribution with mean 0 and variance 1.
What percentage of the area of a normal standard distribution falls between z-1 and z -0.65?
-0.35
What percentage of a normal distribution is located in the tail beyond a z-score of z - 1.20?
11.51% of the distribution.
What is the different between standard normal distribution and normal distribution?
A normal distribution can have any value for its mean and any positive value for its variance. A standard normal distribution has mean 0 and variance 1.
Distinguish between binomial distribution and normal distribution?
Normal distribution is the continuous probability distribution defined by the probability density function. While the binomial distribution is discrete.
