100
85, 87, 89, 91, 93 and 95.
93
The numbers 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99 and 100 are composite (including the boundaries).
number of composite numbers between 81 and 100 = 15composite numbers between 81 and 100 = 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99
80, 81, 82, 84, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.
The median for 85, 93, 95, 96, 98, 99, 100, 100 is 97. The number in the middle is 96, and 98. Add - 96 + 98 = 194 Divide - 194 ÷ 2 = 97
80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100
The answer is 90.To find the average;Add the numbers together (92+85+91+89+93 = 450)Divide this total by how many numbers you have (450 / 5 = 90)The answer is your average or mean.

86 is the mean of 85, 91, 76, 85, and 93.
To analyse data, it is best to first order the data from smallest values to largest values. In this case, that would be: 85, 93, 95, 96, 98, 99, 100, 100. The range is simply the largest number less the smallest. So in this case 100-85, which comes out at 15. Thus the range of the data set in the question is 15.
