Ten athletes take part in both the 100 metre race and the triple jump, and their results are displayed in the scatter diagram.
Axes: the vertical axis is labelled 'Time for 100 m (seconds)' from 12.4 to 13.4, and the horizontal axis is labelled 'Distance in the triple jump (m)' from 14.5 to 15.5.
(a)[1]
One of these athletes records 15.12 m in the triple jump. Write down his time for the 100 metre race.
(b)[1]
Plot these points on the scatter diagram.
(c)[1]
Use the scatter diagram to draw a line of best fit.
(d)[1]
What kind of correlation does the scatter diagram show?
