The relevant data can be found in the Excel file provided separately and named: "International Motoring Organization 2023." CASE STUDY 04/2_2023 Hypothesis Testing I Engineering studies claim that, on average, the vehicle fuel economy exceeds 25 mpg. Do the data provide significant support for this study? Use a 5% significance level and both the critical value approach (classical approach) and the p- value approach to test this study. Your presentation should outline: - - how this problem was tackled, the methodology used, the justification for the solution reached and an interpretation of your results
