It is basically a function whose integral across an interval (say x to x + dx ) gives the probability of the random variable X taking the values between x and x + dx. A normal distribution is a statistical phenomenon representing a symmetric bell-shaped curve. Normal Distribution: The normal distribution, also known as the Gaussian or standard normal distribution, is the probability distribution that plots all of its values in a symmetrical fashion, and . What are five applications of normal distribution? Students will estimate descriptive measures for the sampling distribution and use those measures to approximate the simulated sampling distribution by selecting the mean and standard deviation for overlaying a normal curve. Example 1 Given the probability variable X following the normal distribution N (4,32), find the following probabilities. Important This function has been replaced with one or more new functions that may provide improved accuracy and whose names better reflect their usage. The integral of the rest of the function is square root of 2xpi. Every normal random variable X can be transformed into a z score via the following equation: z = ( X - ) / where X is a normal random variable, is the mean of X, and is the standard deviation of X.
