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. Question 2: If the value of random variable is 2...
Some of the important properties of the normal distribution are listed below: 1. In a normal distribution, the mean, median and mode are equal.(i.e., Mean = Median= Mode). 2. The total area under the curve should be equal to 1. 3. The normally distributed curve should be symmetric at the centre. 4. There should be exactly half of the values are to ...
The normal distributions are closely associated with many things such as: 1. Marks scored on the test 2. Heights of different persons 3. Size of objects produced by the machine 4. Blood pressure and so on.
