Copy the following monthly return data for Tesla Inc. and S&P 500 Index to your Excel file:   S&P 500 Tesla Inc. 03/25 -5.75% -11.54% 02/25 -1.42% -27.59% 01/25 2.70% 0.19% 12/24 -2.50% 17.00% 11/24 5.73% 38.15% 10/24 -0.99% -4.50% 09/24 2.02% 22.19% 08/24 2.28% -7.74% 07/24 1.13% 17.28% 06/24 3.47% 11.12% 05/24 4.80% -2.84% 04/24 -4.16% 4.26% 03/24 3.10% -12.92% 02/24 5.17% 7.79% 01/24 1.59% -24.63% 12/23 4.42% 3.50% 11/23 8.92% 19.54% 10/23 -2.20% -19.73% 09/23 -3.65% -3.05% 08/23 6.47% -3.50% 07/23 0.25% 2.16% 06/23 1.46% 28.36% For the data above, calculate the correlation, covariance, slope, intercept, and R-squared in Excel. Choose the right answer for each from the drop-down menus below.  The slope coefficient of the regression analysis, where Tesla 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 Tesla 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 Tesla 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.
