Question:
2. If all measurements in a data set are multiplied by a fixed number d, the deviations (x - ) get multiplied by d. Consequently, s2 gets multiplied by d2, and s by |d|. (The standard deviation is never negative.)
Verify these properties for the data set
taking c = 4 in property (1) and d = 2 in (2).
