Data from gapminder.org on 184 countries was used to examine if there is an association between (average) female life expectancy (that is, the average lifespan of women in the country) and the average number of children women give birth to for the year 2019. A scatterplot of the data and a regression table from the Corr/Regression applet follows.
-Which of the approaches to a test of the regression slope are valid?
A) Simulation-based test
B) Theory-based test
C) Both A and B
D) Neither A nor B

C) Both A and B 
D) Neither A nor B

Quizplus · Accepted Answer

Both simulation-based and theory-based tests are valid approaches to testing the regression slope. Simulation-based tests use resampling methods, while theory-based tests rely on statistical theories and assumptions.
