1. 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 10 represents the best possible life. The responses were normally distributed, with a mean of 5.4 and a standard deviation of 1.9.

In a recent year, the scores for the reading portion of a test were normally distributed, with a mean of 20.2 and a standard deviation of 5.7. (a) Find the probability that a randomly selected high school student who took the reading portion of the test has a score that is less than 19. The probability of a student scoring less than 19 is (Round to four decimal places as needed.)(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 D. (Round to four decimal places as needed.)
