Description
Test a machine that randomly packages two types of fruit jubes: kookaburra and kiwi. Notice that each jube type is equally likely to be produced within a packet of 12 jubes. Look at patterns in sequences of jube types such as 3 kiwi jubes occurring in a row. Analyse the results of large samples. Compare the longest runs of any jube type. Identify the longest run most likely to occur in a packet. This learning object is one in a series of 17 objects.
Objective
1. Students analyse data about random events to test conjectures about variation.
2. Students interpret frequency graphs to compare experimental results with theoretical probabilities.
3. Students compare the shape of theoretical and experimentally derived data distributions.
4. Students relate the shape of data distributions to statements about sample variation and sample size.
