The question, in short

Using a stem-and-leaf diagram of 30 type A orange masses in grams, complete the range for type A and compare type A with type B masses using the table.

Summarised in our own words. Use the official paper for the exact wording and the diagram.

Part (a) · 1 mark

Find the range in grams of the type A masses from the stem-and-leaf diagram and complete the table.

  1. 1Largest = 218 g, smallest = 176 g
  2. 2Range = 218 − 176 = 42

Answer42

Part (b) · 2 marks

Using the completed table, give two comments comparing type A orange masses with type B orange masses.

  1. 1Mean A = 195.7 g < mean B = 215.8 g, so type A masses are lighter on average
  2. 2Range A = 42 g > range B = 35 g, so type A masses are more varied (less consistent)

AnswerType A masses lighter on average Type A masses more varied/less consistent
