This assignment delves into a quantitative analysis of Boeing stock returns using regression analysis. It investigates the relationship between Boeing's stock returns and market risk, represented by beta. The analysis involves building a linear regression model, interpreting the results including confidence intervals for the slope coefficient (beta), and testing for normality of residuals. The goal is to determine if Boeing's stock returns are consistent with the Capital Asset Pricing Model (CAPM) by assessing the statistical significance of its beta.
