(c) Sarah can't remember which boxplot belongs to which set of balls . State one way in which she could check by looking at the data for each set of golf balls . [1] (d) Sarah realises that the top boxplot represents the data for the current golf balls , and the bottom boxplot represents the data for the new golf balls . She tries to interpret what the boxplots are telling her by making the statements below. For each one, state whether you agree or disagree with her interpretation, and explain why you think that she is correct or incorrect (i) 'On average, the distance travelled by the new golf balls was less than the distance travelled by the current ones. [2] (ii) 'There was less variation in the distances travelled by the current golf balls than in the distances travelled by the new golf balls." [2] (iii) 'More than half of the current golf balls travelled a distance greater than the median .' [2] (e) Use the boxplot for the current golf balls to say whether the data are symmetrical or skewed. If the data are skewed, then state whether they are skewed to the left or skewed to the right, explaining your reasoning briefly. [2] (f) Sarah creates (poorly presented ) histograms for each of the two datasets , shown in Figures 3 and 4 below 275 210 319
