there are 5 whole numbers in a data set. the least number is 14 and the greatest number is 25. the mean and median are both 19.what numbers could be the values in the data set?
14 19 25.
I do not know how to get the other two missing numbers in the data set? Please advice me.
well, if you have 5 numbers whose mean is 19, then they must add up to 5*19 = 95
Your sum so far is 58
So, you need two more numbers which add up to 37. Since your median is 19, you need one less than 19 and one greater than 19.
So, how about
14 17 19 20 25
You can surely find other pairs which also work.posted by Steve
