Answer 1:-
a) Normal Distribution:
Normal or Gaussian distribution is a continuous probability distribution. Normal
distribution is such a type of distribution where random variables are normally distributed. The
normal distribution is informally bell shaped curve in nature. The probability density of the
normal distribution is given by-
Here, μ= The mean or average or expectation of the distribution.
σ = Standard deviation of the distribution.
σ2 = Variance of the distribution.
Normal distribution is symmetric in nature that means it has equal concentration of mass
towards both the sides of the curve. Symmetry means that one-half of the distribution is a minor
image of the other half. The skewness of normal distribution is 0 (Harvey and Siddique 2000).
We calculate the skewness of other curves with respect to normal distribution.
