Please answer the question The standard deviation ot 10 observations a. , a, , _ is 25. each observation is multiplied by 2 aM tmen increased by SO, the new standard deviation bewmes B) 25 (C) 100 (0) 10


Dear Student,

The answer to this question is option B : 50

When we multiply a constant to each observation of a data set, the standard deviation of the data set also gets multiplied by the same constant. However, when we add a constant to each of the observations in a data set, the standard deviation of the data set remains the same.
