5th grade is NOT the School Subject. You must identify it correctly for the correct volunteer teacher to read your post. It is not I!

Your Max (highest number) = 18
Your range is 13 so your minimum number in your set =5
You need the mean to = 12 so all twelve numbers in your set have to equal 144 so that the 12 individual numbers will have a mean of 12 (144/12=12).
The mode = 7 - so 7 is going to occur more than once (the mode is the number occurring most often).
A SAMPLE answer is: 5-7-7-7-11-13-13-15-15-16-17-18 (totaled=144/12 = mean of 12); 7 occurs three times so is the mode. There are other combinations
find the range of 78, 9, 100, 6 ?
