Identifying correlation between variables

You saw that adding a trendline to a scatter plot is a great way to get a sense of the strength and direction of a relationship between variables.

An app has been provided for you to display scatter plots with a trendline for data about cities. The data point represents a city, and its location in the plot is determined by the cost of a bottle of water and a monthly gym membership in that city.

Your task is to describe the Pearson correlation coefficient for the cost of a bottle of water (£) as the dependent variable and annual hours worked as the independent variable.
