Chapter 5, Problem 5.12Q

Interpretation Introduction

Interpretation:

The distribution for the given condition should be calculated and whether these distribution appear as normal or not is to be identified.

Concept introduction:

Normal distribution is bell shaped density factor helps in calculating the value of distribution based on the number of variables.The formula for normal distribution is given below:

  $\frac{1}{\sigma \sqrt{2\pi }}{e}^{\frac{-1}{2}\left(\frac{x-\overline{x}}{\sigma }\right)}$

Where,

  $\sigma =$ Standard deviation

  $\overline{x}$ = Mean

Standard normal distribution is a type of normal distribution. It occurs when the normal distribution has the value of mean equals to zero and the value of standard deviation is equal to one.
