the average is 16 11+16+15+22=64 64/4=16

One possible set is {-3.5, 6.5, 9.5, 11.5}
All except 15
The range is the maximum minus the minimum. So if there was a number set of 2,5,7,7,8,12, and 15, the range would be 15-2, or 13.
One possible set is {9, 9, 10, 11, 12, 15, 18}
We can't answer that without knowing the set of numbers.
The range is the difference between the maximum and minimum observation in a set of data. Thus the range is 12 (23 - 11).
11
the average is 16 11+16+15+22=64 64/4=16
There is no such data set for 7 numbers. With the maximum at 35 and the range 20, the mode (average) will always be more than 21, even with the lowest numbers possible. e.g. 15 15 15 24 24 24 35 sums to 152, which is 5 higher than the necessary 147 (21 x 7) So you need at least 11 numbers such as 15 15 15 15 15 24 24 24 24 25 35, keeping 24 as the median and the average 21 (231/11).
16
Any one of the infinite set of numbers of the form 1320*k where k is an integer.
Range = 15 - 2 = 13
One possible set is {-3.5, 6.5, 9.5, 11.5}
That appears to be one big number. I guess there are supposed to be spaces to separate the numbers. Looking at the number, it looks [to me] like the set of numbers is most likely to be {15, 16, 19, 14, 20, 18, 18, 18}. range = highest_number - lowest_number = 20 - 14 = 6.
What Five Numbers have a range of 5 a median of 16 and a mean of 15
