Suppose n and k denote the sample size and number of regressors respectively. What degrees-of-freedom adjustment is required while calculating the standard error of the regression (SER) from the sum of squared residuals (SSR)? A. A division by n - k-1. B. A division by n - k + 1. C. A multiplication by nk + 1. D. A multiplication by n - k. A group of randomly selected 150 automobile dealers across the automobile industry was surveyed and information about their advertisement expenditure (X₁), the average price of the cars they sell (X₂), and the total number of cars sold in a particular year (Y) (in thousands) was collected. The estimated OLS regression is: Y₁ = 10.25 +1.13X₁,-0.36X2; + U¡› where Y¡, X₁₁, and X₂, denote the predicted value of the number of cars sold, the advertisment expenditure, and the average price of the cars sold by the th dealer, respectively. 1/² Calculations show that: Based on the above information, the standard error of regression (SER) will be (Round your answer to two decimal places). 150 2 Σ (y₁ - y)² = Y; i=1 = 155.23.
