Choose the right answer for each from the drop-down menus below. The slope coefficient of the regression analysis, where Apple Inc. stock returns are the dependent variable and S&P 500 returns are the independent variable, is [slope]. The intercept coefficient of the regression analysis, where Apple Inc. stock returns are the dependent variable and S&P 500 returns are the independent variable, is [intercept]. The R-squared for the regression analysis, where Apple Inc. stock returns are the dependent variable and S&P 500 returns are the independent variable, is [R-squared]. Make sure to answer all five questions! Save your work in MS Excel and submit your Excel file at the end of the exam.
