Variance and standard deviation of a discrete random variable
We learn how to calculate the mean and standard deviation of a discrete random variable. The concept of a random variable is explained, along with methods to calculate its expected value (mean) and measure its spread (variance and standard deviation). A practical example makes the concept easier to understand.

SOLVED: The formula to calculate the standardized normal random variable is (x - μ) / σ, where μ is the mean and σ is the standard deviation. If μ = 5000 and σ = 50, the z-value of x - 5025 is -0.5. If the z-score of a normal distribution is 2.5, the mean of the distribution is 45, and the standard deviation of the normal distribution is 3, then the value of x for the normal distribution is 97.5.
