A researcher has estimated the following multiple regression model to investigate the determinants of capital structure in an emerging market based on data from 2016.
LEV = 1.32 – 0.10TANG - 0.28PROFIT + 0.19GROWTH + e (0.92) (0.03) (0.25) (0.04)
Residual sum of squares = 200Total sum of squares = 620Number of Observations = 90Standard errors of the coefficients are given in parentheses.
The variables are:LEV = Leverage (total debt to total assets).TANG = Tangibility (net fixed assets to total assets). PROFIT = Profitability (net income to total assets). GROWTH = Firm growth (Percent change in sales). e = residual
Construct a 95% confidence interval for the slope coefficient for ‘TANG’ and interpret the result. The critical t value is 1.96 at the 5% significance level for a two-tailed test.

- An economy is based on three sectors: Agriculture, Manufacturing, and Energy. Production of a cedi’s worth of agriculture requires inputs of GH¢0.2 from agriculture, GH¢0.15 from manufacturing, and GH¢0.2 from energy. Production of a Ghana cedi’s worth of manufacturing requires inputs of GH¢0.40 from agriculture, GH¢0.10 from manufacturing, and GH¢0.10 from energy. Production of a Ghana cedi’s worth of energy requires inputs of GH¢0.3 from agriculture, GH¢0.10 from manufacturing, and GH¢0.10 from energy. There is a final demand of GH¢10 billion for agriculture, GH¢15 billion for manufacturing, and GH¢20 billion for energy. (a) Formulate the system of linear equations which must be solved to give the combination of output for the three sectors that will satisfy the final demand. (b) Write the equations in matrix form (c) Determine the output for each sector using the inverse matrix method.arrow_forwardScalia Law is trying to gain a better understanding of the determinants of bar passage rates.
