Answer:

value that can be added to the set  without changing its mean is:

15

Step-by-step explanation:

we are given the data set:

{4, 10, 14, 18, 22, 22}

Mean of this set is= (4+10+14+18+22+22)/6

                             = 90/6

                             = 15

  • if we add 0 in this set then

     new mean=90/7=12.86

  • if we add 15 in this list then

           new mean = 105/7=15

  •   if we add 16 in this list

           new mean=106/15=7.066

  •      if we add 22 in this list

           new mean=112/15=7.466

  Hence, on adding 15 the mean of the data set do not change
