This report presents an analysis of the relationship between poor maintenance facility practices and commercial aviation delays. The study utilizes regression analysis and ANOVA to test the hypothesis. The report begins by defining study parameters, distinguishing between population parameters and sample statistics. It identifies the dependent variable (carrier delay) and the independent variable (weather) and explains how weather events like thunderstorms and lightning contribute to delays. The report includes regression statistics, including Multiple R, R Square, Adjusted R Square, and Standard Error, and interprets their significance. The ANOVA analysis is discussed, and the coefficients are used to build a linear regression equation. The hypothesis is tested, and the report concludes by either accepting or rejecting the null hypothesis based on the analysis. The student concludes that the null hypothesis is rejected, supporting the alternative hypothesis that there is a relationship between the maintenance facility practices and commercial aviation delays.
