Answer:
New mean will be 12
And no change in standard deviation
Step-by-step explanation:
We know the relationship between the two mean and standard deviation
[tex]\sigma=\frac{\sqrt{x-x_i}}^2{n}[/tex]
[tex]\sigma=\text{standard deviation},x=mean,n=\text{number of observations}[/tex]
If we add 2 to each value of x that means the mean will become n will become 2n and since we are adding 2 to each value
The new mean will become 12
And there will be no change in the standard deviation because of equal change in the each data.
