10
20
25
Q4.
Referring to the scatter diagram above, which of the following statements is likely to be TRUE? Select one
It's impossible that only 5 ice creams were sold when the temperature was 25 degrees - the person plotting the graph must have made a mistake!
More ice creams sold caused the temperature to increase
Since there are two different numbers of ice creams sold when the temperature is 25 degrees, there must be a mistake on the graph
