A tyre manufacturer has chosen 48 tyres at random from a production line and issued them to taxis
for testing. Assume that the 48 numbers you have selected refer to the number of thousands of
kilometres travelled during the life of each tyre. (For example, a value of ‘32’ represents 32 000 km of
travel.)
Which statistical average would be most appropriate to describe the ‘average’ tyre life in an
advertising campaign? Justify your decision.
