Answer 2

Answer:

If the S.D. of a data is 3.6 and each value of the data is divided by 3 , then find the new variance and new standard deviation.

Step-by-step explanation:

If the standard deviation of a data is 3.6, and each of the data is divided by 3 then the new standard deviation is also divided by 3.

∴ The new standard deviation = 3.6/ 3 = 1.2

The new variance = (standard deviation)2 = σ2 = 1.22 = 1.44
