The scatterplot shows a positive linear relationship between optimism and life satisfaction, where as one variable increases, the other variable also tends to increase. Therefore, we can conclude that as optimism increases, life satisfaction also increases. However, we cannot infer a causal relationship between the two variables from this observation. Option A is incorrect because we cannot infer causation from this figure. Option C is also incorrect as the relationship is positive, not negative. Option D is not supported by the data given in the figure.
