In a recent study on world happiness, participants were asked to evaluate their current lives on a decimal scale from 0 to 10, where 0 represents the worst possible life and 10 represents the best possible life. The mean response was 5.4 with a standard deviation of 2.1. Assume the distribution can be approximated by a normal distribution. (a) What response represents the 88th percentile? (b) What response represents the 65th percentile? (c) What response represents the first quartile?
