QuestionThe scatterplot of the data is below. Describe the type of correlation between GDP and CO2\mathrm{CO}_{2} emissions. negative no correlation positive
Question 2 2 pts
The correlation between GDP and carbon dioxide emissions is r=0.912\mathrm{r}=0.912. Is the correlation significant at α=,05\alpha=, 05 ?
Give the critical value from the table: \square Is the correlation significant? (yes or no) \square

Studdy Solution
Conclude whether the correlation is significant:
Since the calculated r (0.912) is greater than the critical r (0.361), we can conclude that the correlation is significant at the α = 0.05 level.
Therefore, the answers to the questions are:
1. The type of correlation between GDP and CO₂ emissions is positive.
2. Critical value from the table: 0.361 (assuming n = 30) Is the correlation significant? Yes
Note: The exact critical value may vary depending on the actual sample size, which was not provided in the question. Always use the correct sample size and corresponding degrees of freedom when looking up critical values in practice.
