1.1. Belle records the height, in centimetres, and the mass, in kilograms, of some goats.
Some of her results are shown in the scatter diagram.

The table shows four more results.

Plot these points on the scatter diagram.

1.2. What type of correlation is shown in this scatter diagram?

1.3. The mean height of all the goats is 29.5 cm and the mean mass is 33.2 kg.

i) Draw a line of best fit on the scatter diagram.
