Quantitative Methods for Accounting & Finance
Answer the following hypothesis questions:
1. How does the winning age at different categories? Calculate the Mean, Median, Mode, Standard Deviation and Coefficient of Variation of winning age for different category. Compare the figures and explain that what conclusions you can draw from these analyses? Draw a box and Whisker plot for each category and comment on the shape of the graph.
2. Determine if average age for Physics is less than average age for Chemistry.
Compare the result with question 1. Does the result confirm your previous findings? (Follow the hypothesis testing steps, 0.05 level of significance, assuming “equal variances” of populations).
3. To get a more complete picture, we should look at how the age of winners have changed over time. Using a line chart to present the age of the winner (Y variable on vertical axis) and year (X variable, horizontal axis) for different category, comment on the trend for different category.
