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


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.
Use the linear equation “slope of a line” to find the slopes of the given points. m= y2-y1/x2-x1
