If the sample size, n, is "large" and both np and n(1 - p) are large enough, the sampling distribution of the sample proportion p = X/n will be approximately a Normal distribution with mean = p and standard deviation: \(\sigma =\sqrt{\frac{p(1-p)}{n}}\) This applet illustrates that important fact by allowing you to generate individual samples or thousands of samples with the specified . See this method for calculating the PDF of the product of two independent continuous random variables, in terms of their PDFs. Take $X$ to be normally distributed with mean and variance $X\sim N(2, 3).$. Found inside Page 275If the Statistical Package for the Social Sciences ( SPSS ) ( Norusis 1992 ) is used , these expected normal scores can By multiplying / dividing the distribution by a constant , then adding / subtracting a constant , the original of X, multiply and divide by ett, You can modify the standard deviation of your normally distributed random variable by multiplying a constant to your random variable (where the constant is your desired standard deviation).

Why is it that when you add normally distributed random variables the variance gets larger but in the Central Limit Theorem it gets smaller? Then, the distribution of the random variable = + is called the log-normal distribution with parameters and .These are the expected value (or mean) and standard deviation of the variable's natural logarithm, not the expectation and standard deviation of itself. By definition any Humphreys distribution with Pm = 0.5 is a normal distribution with Standard deviation = (Xi - Ni)/6 = 4,000/6 = 666.66666. x is normally ditsributed with a mean of 500 and a standard deviation of 100.
