Please explain how to find the answer

Consider the following estimated models: Model 1: y = 10 + 4.4x Model 2 y = 2 + 23 In(x) Model 3: In(y) = 3.0 + 0.1%; se = 0.07 Model 4: In() = 2.6 +0.6 In(x); se = 0.05 a. Interpret the slope coefficient in each of the above estimated models, when x increases by one unit in Models 1 and 3 and by 1% in Models 2 and 4. (Round your answers to 2 decimal places.) units units. Model 1:9 Model 2: Model 3: 9 Model 4:9 by by about by about by about percent. percent. b. For each model, what is the predicted change in y when x increases by 5%, from 10 to 10.5? (Do not round Intermediate calculations. Round final answers to 2 decimal places.) units units Model 1: Model 2:9 Model 3: Model 4:9 by by by by percent. percent
