Answer:

  • mean: 70.4
  • median: 67
  • mode: no mode
  • range: 55

Step-by-step explanation:

The mean is the average value: the sum divided by the number of numbers. The median is the middle number when they are written in increasing order. The mode is the number that appears most often. The range is the difference between the highest and lowest values.

__

Sorted into increasing order, the numbers are ...

  43, 57, 67, 87, 98

mean

The total of these values is

  43 +57 +67 +87 +98 = 352

The mean is this sum divided by the number of contributors:

  mean = 352/5 = 70.4

__

median

The median of the 5 numbers is the middle (3rd) one:

  median = 67

__

mode

The mode is the most-repeated number. All of the numbers show up exactly once, so there is no mode.

  mode: none

__

range

The range is the difference between the highest and lowest values:

  range = 98 -43

  range = 55
