Answer:
First we need to sum total those data
8+6+9+4+3+5+6+3+8+4+1+4+4+5
=70
then we should divide the sum number by total number which is 70 divided by 14
which is equal to 5
so the mean or average of this data Is 5
and if all data are added by 2 then the sum becomes 70+(2×14)
=70+28
=98
so now the mean is 98 divided by 14 which is equal to 7
I hope this helped you

Answer:
5;7
Step-by-step explanation:
Mean=Sum of observations ÷ Number of observations
Sum of observations=8+6+9+4+3+5+6+3+8+
4+1+4+4+5
=70
Number of observations=14
Mean =70/14
=5
If 2 is added to each number , then the
new series will be 10,8,11,6,5,7,8,5,10,6,3,6,6,7.
Sum of observations =98
Number of observations=14
Mean=98/14
=7.
