Question

In 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 represents the best possible life. The responses were normally distributed, with a mean of 6.2 and a standard deviation of 1.9. Answer parts (a)-(d) below 

(a) Find the probability that a randomly selected study participant's response was less than 4. 

The probability that a randomly selected study participant's response was less than 4 is 0.1230 (Round to four decimal places as needed.) 

(b) Find the probability that a randomly selected study participant's response was between 4 and 6 

The probability that a randomly selected study participant's response was between 4 and 6 is 0.3332 (Round to four decimal places as needed.) 

(c) Find the probability that a randomly selected study participant's response was more than 8. 

The probability that a randomly selected study participant's response was more than 8 is(Round to four decimal places as needed)
