T include S and they could have the exact numbers or T could have more
A=S/N of S and T could be the same BUT S has only numbers which could be 1 and the SD is just 1
And T could have the exact numbers, the average but the SD could be 5
Or vice-versa
The answer is D
A=S/N of S and T could be the same BUT S has only numbers which could be 1 and the SD is just 1
And T could have the exact numbers, the average but the SD could be 5
