Question 1: Calculate the probability density function of normal distribution using the following data. x = 3, μ = 4 and σ = 2. Solution: Given, variable, x = 3. Mean = 4 and. Standard deviation = 2. By the formula of the probability density of normal distribution, we can write; Hence, f(3,4,2) = 1.106.

WebJul 24, 2016 · For the normal distribution we know that approximately 68% of the area under the curve lies between the mean plus or minus one standard deviation. Therefore, 68% of the area under the curve lies between 23 and 35. We also know that the normal distribution is symmetric about the mean, therefore P(29 < X < 35) = P(23 < X < 29) = … WebMay 12, 2024 · The area under the normal curve is equal to 1.0 (or 100% of all scores will fall somewhere in the distribution).
