UP to a whole number.

Expert Solution

Step 1

For a doctoral dissertation, it is decided to study the social well-being of100,000 people. To complete the questionnaire that measures social well-being the data is collected. higher numbers indicate more positive well-being. The mean( $μ)$ of the score is 100 points and s.d. is 20( $σ)$ points.

Let X be a random variable, that represents the proportion of well-being, that follows a normal distribution.

$μ = 100 σ = 20$

So, X $~ N (100, 20^{2})$
