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
What Five Numbers have a range of 5 a median of 16 and a mean of 15
four and sixteen16 - 4 = 1216 + 4 = 20 then 20 / 2 = 10Half of 12 is 6, therefore the two numbers 10 - 6 = 4 and 10 + 6 = 16 will have a mean of 10 and a range of 12.Further numbers can be added between 4 and 16 as long as their mean is still 10, eg the data sets:{4, 16}{4, 10, 16}{4, 8, 12, 16}{4, 8, 10, 12, 16}{4, 7, 9, 14, 16}all have a mean of 10 and a range of 12. There is an infinity of such sets.
9 15 15 15 16 (five data) Range = 16 - 9 = 7 Mean = (9 + 15 + 15 + 15 + 16)/5 = 70/5 = 14 So we have: (9 - 14)2 = (-5)2 = 25 (the square of the difference of data value and the mean value) (15 - 14)2 = 12 = 1, 3(1) = 3 (16 - 14)2 = 22 = 4, the sum is 32 The standard deviation = √(32/5) ≈ 2.5
115/10 = 11.5
add them all up and divide by 2 ! 7+14+10+14+29+16+15=? ?/2=? Answer:52.5->53
Mean: 11.6 Median: 12 Mode: 10, 12, 15, 16, 5 Range: 11
12, 14, 15, 16, 16, 17 The median is 15.5 The mode is 16 The range is 5 The mean is 15
What Five Numbers have a range of 5 a median of 16 and a mean of 15
6, 10, 11, 12, 14, 14, 15, 22 mean: 13 median: 13 mode: 14 range: 16
the range is 10
Mean: 13.6 Median: 15 Mode: 16, 18, 15, 9, 10
Range = Maximum - Minimum = 20 - 8 = 12.
(0, 2, 15, 16, 17) 0+2+15+16+17 = 50 50/5 = 10 The median is 15, the mean is 10.
mean(18, 23, 39, 10, 22, 17, 16, 15) = (18 + 23 + 39 + 10 + 22 + 17 + 16 + 15) ÷ 8 = 160 ÷ 8 = 20
four and sixteen16 - 4 = 1216 + 4 = 20 then 20 / 2 = 10Half of 12 is 6, therefore the two numbers 10 - 6 = 4 and 10 + 6 = 16 will have a mean of 10 and a range of 12.Further numbers can be added between 4 and 16 as long as their mean is still 10, eg the data sets:{4, 16}{4, 10, 16}{4, 8, 12, 16}{4, 8, 10, 12, 16}{4, 7, 9, 14, 16}all have a mean of 10 and a range of 12. There is an infinity of such sets.

29. To find range, you subtract the lowest term, from the largest term. 39-10=29
