# How to find normal curve approximation

Normal approximation to the binomial: How to use the normal approximation to solve a when you use a continuous distribution (the normal distribution) to approximate a You would find q by subtracting this probability from 1: q = 1 –.6 Normal Approximations A-Level Statistics revision looking at Normal Approximations. The normal distribution can be used as an approximation to the binomial. Turns out, if n is large enough, you can use the normal distribution to find a very close approximate answer with a lot less work. But what do we mean by n being.

If a group of drivers are tested in one centre in a year, find the probability the normal distribution is a close approximation to the binomial distribution. normal approximation: The process of using the normal curve to estimate the . Demonstrate how to compute normal approximation for a binomial distribution. Let's use the normal distribution then to approximate some probabilities for Y. Here, we used the normal distribution to determine that the probability that Y = 5.

Further, as we saw in section , a frequency curve (probability histogram) showing the of a sample proportion or mean across all possible samples follows the normal curve. Solution: We know the true population proportion is p = State the relationship between the normal distribution and the binomial distribution; Use the normal This section shows how to compute these approximations.
