A survey showed that the more playtime parents spend with their children, the higher their scores on a scale of parental satisfaction. Which of the following correlation coefficients would best reflect the relationship between playtime and parental satisfaction? 0.00 -0.72 1.23 0.85

1. A positive correlation means that as one variable increases, so does the other. In this case, as playtime increases, parental satisfaction increases. 2. The correlation coefficient must be between \(-1\) and \(1\). Among the options, \(1.23\) is not within this range and therefore is not valid. 3. A correlation coefficient of \(0.00\) would indicate no correlation, while \(-0.72\) would indicate a strong negative correlation — both of which do not reflect the positive relationship described. 4. The coefficient \(0.85\) is the only option that represents a strong positive correlation. Thus, the best reflection of the relationship is \(0.85\).
