Health researchers and economists believe that the impact of the COVID-19 pandemic is far worse in third-world nations as compared to developed countries. This difference is potentially brought by the gap in health services, vaccination rate, and adherence to health protocols. To assess such claim, data on COVID-19 related deaths from 2020 to 2021 was recorded from 165 sample countries. Data on GDP per capita and income classification of the country was also included.Use Jamovi and determine the test statistic.

  1. Researchers believe that the country's GDP can be used to predict COVID-19 deaths. Using data from 2020 to 2021 deaths, can we say that GDP per capita is a significant predictor of COVID-19 deaths at 5% level?
  2. Use the variable Deaths = Deaths_2020 + Deaths_2021, representing deaths per million from 2020-2021. This will be used as the outcome variable of the model.
  3. Include necessary assumption checks and model validation.
  4. Include necessary descriptive statistics.
  5. Provide proper discussion and interpretation of the result.
