The range of the numbers is the largest minus the smallest:
largest is 29,
smallest is 17
⇒ range = 29 - 17 = 12
Mean = 20 Median = 18 Mode = 18 Range = 9
16, 17, 18, 19
It is 18, the middle number when they are in order.
The mode is the number which occurs most - so this is 20 The median is the middle number if you write them all in numerical order..... 5, 13, 13, 15, 18, 20, 20, 20 The answer is 16.5 which is in the middle of 15 and 18 To find the mean you add all the numbers up 5+13+13+15+18+20+20+20=124 then divide by the number of numbers in the range (8). 124/8 = 15.5
18, 20, 22, 24, 26, 28
5
18, 23, 10, 39, 22, 17, 16, 15 Mean = (18 + 23 + 10 + 39 + 22 + 17 + 16 + 15)/8 = 20 Lowest Number in set is 10 Highest Number in set is 39 Range = (39 - 10) = 29
35 - 18 = 17 17/n = 20 n = 17/20 = 0.85
Since 17 is a prime number, the greatest common factor of 17, 18, and 20 is 1.
Mean = 20 Median = 18 Mode = 18 Range = 9
16, 17, 18, 19
It is 18, the middle number when they are in order.
No number appears more than once, so there is no mode.
The range is 17: 20 - 3 = 17
The range is 12 and the standard deviation is 3.822448314.
18-the correct number should be 20.
