Enter mean (average), standard deviation, cutoff points, and this normal distribution calculator will calculate the area (=probability) under the normal distribution curve. Normal distribution or Gaussian distribution (named after Carl Friedrich Gauss) is one of the most important probability distributions of a continuous random variable.
Then we can find the probability using the standard normal calculator or table. Households of more than 3 people are, of course, quite common, but it would be extremely unusual for the mean size of a sample of 100 households to be more than 3.

Then we can find the probability using the standard normal calculator or table. Comment: As long as the sample is truly random, the distribution of p-hat is centered at p, no matter what size sample has been taken.

The calculator allows area look up with out the use of tables or charts. In addition it provide a graph of the curve with shaded and filled area. The z-score is the number of standard deviations from the mean. The standard normal distribution is a normal distribution with a standard deviation on 1 and a mean of 0.
Note: The normal distribution table, found in the appendix of most statistics texts, is based on the standard normal distribution, which has a mean of 0 and a standard deviation of 1.To produce outputs from a standard normal distribution with this calculator, set the mean equal to 0 and the standard deviation equal to 1.
The final exam scores in a statistics class were normally distributed with a mean of and a standard deviation of . Find the probability that a randomly ...
