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
