From the bar - graph, the number of goals for Ann is \(4\), for Ben is \(5\), for Mia is \(2\), for Leo is \(4\), and for Zoe is \(4\).

Step2: Calculate the total

The total number of goals \(T=4 + 5+2 + 4+4\).

A line graph is used to show the change or trend of a variable over time. Since the fitness trainer wants to display the trend in the client's running - speed improvement over time (weekly sessions over three months), a line graph is appropriate. A circle graph (pie chart) is used to show the proportion of parts to a whole. A pictograph uses pictures to represent data counts. A bar graph is good for comparing discrete data values, not for showing trends over time.

\(20\) (the fourth option)
