Hi Petr, thanks for your answer.
First of all it's not homework I am a student and need to analyse cancer data using linear models. I looked into that topic since a week now and still struggling in interpreting some of the R output that is why I was asking for help here. I don't quite understand your answer because the 180/190 values belong to height and not to weight. What do you want to show with plot(scores,weight). What I can see from the plot is that there is a correlation between the two variables and therefore weight "explains" scores.
