Standard Normal Distribution is a random variable that is calculated by subtracting the mean of the distribution from the value being standardized and then dividing the difference by the standard deviation of the distribution. The Formula of Standard Normal Distribution is shown below: Z = (X –μ...
Given that z is a standard normal random variable, compute P(0 less than or equal to z less than or equal to 0.83). Given that z is a standard normal random variable, compute: P(-1.57 less than or equal to z less than or equal to 0). Let z denot...

where x is a normal random variable, μ is the mean of x, and σ is the standard deviation of x. you can also find the normal distribution formula here. in probability theory, the normal or gaussian distribution is a very common continuous probability distribution. also, read: ...
Discover the purpose of z-scores in statistics and learn the formula to find the z-score. Understand what positive and negative z-scores mean. Related to this Question Given that z is a standard normal random variable, find z given that the area to the ...
In a normal distribution, the mean is zero and the standard deviation is 1. In a binomial experiment, the number of successes is a random variable. If a random variable has a binomial distribution, its standard deviation is given by: 𝜎 = √npq, where mean: 𝜇 = np, n = number ...
Sometimes in this situation, we may need to change the z-score into a random variable with a normal distribution. For this, we would use theformula for z-scores.
