  1. In this dataset men generated a higher week 1 revenue than women, on average.

    • Is this difference in revenue between men and women statistically significant?
    • What is an appropriate statistical test to determine this and what is it's p-value?

  2. In which country is this difference biggest?

  3. Please visualize the relationship between country, gender, and week 1 revenue with an appropriate chart.

  4. Build a linear regression model to predict the week 1 revenue of a user based on the following variables:

    • Gender,
    • Age,
    • Country,
    • day 1 revenue (ie the revenue generated by the user on their registration date).
    • Which of these variables have a statistically significant predictive power according to this model?

  5. What revenues do you expect women from France, Germany, and the UK to generate, assuming they are all aged 40 and all generated £20 on their registration day?
