Normal curve is symmetrical
Web11 de mar. de 2016 · A standard normal curve describes data form a variable that has infinite, or very large, number of possible values distributed among the population. It has certain properties, like: The shape is symmetric; the distribution rises in the middle, and goes down to the left and to the right; the mean is in the middle of the distribution; the mean ... WebIf f (x) is a density function then 0 less than or equal to f (x) less than or equal to 1 b. If F (x) is a cumulative distribution function then 0. Consider a variable x with : Mean of x =10, Variance of x =16 and x has a Normal Distribution Calculate : P (5< x<17) Prove a random variable is a normal distribution.
