Question

044. For a given data the variance is 36. If 3 is added to each observations, what will be the new standard deviation
3
0 (A) 36
O (B) 33
O (C) 39
O (D) 6​

Answer 1

Answer:

d 6 this is the correct answer

Answer 2

Solution: If we add 3 to each observation then no any effect will come to variance.

             Therefore, standard deviation=$\sqrt{variance}$

                                                               = $\sqrt{36\\}$

                                                               = 6

                      option D is the correct answer.
