D) body weight has no causal influence on the reading abilities of children.

Question

Quizplus · Accepted Answer

The positive correlation coefficient of +0.85 indicates that there is a strong relationship between physical weight and reading ability, and specifically that better reading ability is associated with greater physical weight among children. This does not necessarily imply a causal relationship, but it does suggest that the two variables are related in some way. Option A is incorrect as the correlation is strong and positive, indicating a strong statistical relationship between the two variables. Option B is also incorrect as the correlation is positive, suggesting that higher body weight is associated with better reading ability. Option D is also incorrect as the correlation suggests that there is some type of relationship between the two variables.
