Consider the examples above. We have seen that the model \mathrm l\widehat{\mathrm n(Y)} = -1.5 0.56(X) can be transformed to the exponential model to \widehat{\mathrm Y} = (0.223) \cdot (1.75)^{X}, which gives the interpretation that for every increase in X by 1 unit, the average value of Y will increase 75%. Let's consider an increase in X by 2 units. For every increase in X by 2 units, the average value of Y increases ________ . Hint: you do not need R to answer this question.
