Quizplus · Accepted Answer

Line b represents the mean height of the offspring for a given average height of the mother and father. This is because line b is the line of best fit or regression line, which represents the relationship between the two variables (height of parents and height of offspring) and takes into account the overall trend of the data. Lines a and c represent specific values or categories of the data and do not take into account the variability or relationship between the variables.
