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.
Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. Thank you.
Also do not use more than one name. See later post under Bella.
