How to solve normal distribution problems
WebApr 23, 2024 · If a normal distribution has mean μ and standard deviation σ, we may write the distribution as N ( μ, σ). The two distributions in Figure 3.1. 3 can be written as. (3.1.1) N ( μ = 0, σ = 0) and. (3.1.2) N ( μ = 19, σ = 4). Because the mean and standard deviation describe a normal distribution exactly, they are called the distribution's ... WebThe way I understand it, the answer choice would have to explicitly state "The percentage of data below/above the mean/standard deviation" as opposed to "The mean/standard deviation". In a standard normal distribution, the mean (µ) by itself is equal to 0, and the standard deviation (σ) is equal to 1.
