A property market analyst is interested in estimating effect of property lot size (x) on property sale price (y). Which of the following model measures the effect of lot size on percentage changes of sale price. Oa y = a + BiIn(x) +e. O b. all of the models provided in the answers. Oc. In(y) = a + Biln(x) +e. y = a + Bix + B2x2 + e . Oe. In(y) = a + Bixte.Let X be the normal random variable with the mean 0 and standard deviation 2. What is the probability for x taking a value that is less than 0.46? O a. 42.03%. O b. 23.0%. O c. 40.9%. O d. 59.1%. Oe. 18.2%.For time series analysis, if the variable y is observed to be jy = 1, y, = 1.8, y, = -2.1 and y, = 1.1, then Ay, is calculated as: O a. 0.8 Ob. -1 O c. -3.2 O d. 0.3 O e. 3.2
