Hi  

n a recent study on world​ happiness, participants were asked to evaluate their current lives on a scale from 0 to​ 10, where 0 represents the worst possible life and 10 represents the best possible life



Normal and Continuous Distribution

 mean of 5.1 and a standard deviation of 2.4 

P(x < 4) = P(x ≤ 4)   Continuous Distribution

P(x ≤ 4) = .3234

Wish You the Best in your Studies.
