Question

make up a set of 15 numbers with the following landmarks:
maximum: 152
Range: 25
Mode: 139
Median: 142

Answer 1

The median = 142

You need to have 7 numbers above 142 and 7 numbers below 142

Maximum is 152
Range of 25 means the Minimum has to be 152 -25

The mode is a number that occurs more than once, so include 139 two or 3 times.

You can make up the rest of the numbers to fill-in between the minimum and the median and the median and the maximum.

I would be happy to check your final answer.

Answer 2

140 139 139
