There is a relationship between perceived corruption and human development in a country that can be modeled by H(x) = 0.3 +0.28 In x. In this formula, x represents the Corruption Perception Index, where 1 is very corrupt and 10 is least corrupt. The output gives the Human Development Index, which is between 0.1 and 1 with 1 being the best for human development. (a) For country A, x = 5. Evaluate H(5) and interpret the result. (b) The Human Development Index is 0.69 for country B. Find the Corruption Perception Index for country B. (a) H(5)~ (Simplify your answer. Round to two decimal places as needed.)
