Question: Car parking spaces in a city centre are at a premium. The costs of parking a car for a whole day in ten public car parks within the city, and the distances between those car parks and the centre are:

Cost (£) 5 5 7 8 10 12 15 15 18 20

Distance (km) 1.5 1.2 1.0 1.1 0.8 0.5 0.4 0.2 0.1 0.1

1. Assuming that the cost of parking is dependent on the distance the car park is from the city centre, plot the data on a scatter diagram.
2. Find the value of the Pearson correlation coefficient and indicate what conclusions should be drawn from it.
