If the standard deviation of 0,1,2,3...9 is K , then the standard deviation of 10,11,12,13....19 is

The standard deviation for the set of the numbers 1,4,5,7,8 is 2.45. If 10 is added to each number then new standard deviation is

The mean and standard deviation of 10 observations x_(1), x_(2), x_(3)…….x_(10) are barx and sigma respectively. Let 10 is added to x_(1),x_(2)…..x_(9) and 90 is substracted from x_(10) . If still, the standard deviation is the same, then x_(10)-barx is equal to

Consider the following statements : (i) Mean of 100 observations is 50 and standard deviation is 10. If 5 is added to each observation the new mean and standard deviation are 55, 10. (ii) Mean of 100 observations is 50 and standard deviation is 10. If each observation is multiplied by 3 then the new mean and standard deviation are 50, 10/3. The true statements are :
