When a constant k is added to or subtracted from each ontry, the sample mean is unaffected. And the new sample standard deviation is s + k or s-k. respectively When a constant k is added to or subtracted from each entry, the new sample mean is **k or X-k, respectively, and the new sample standard deviation is When a constant is added to or subtracted from each entry, the new sample mean is x+korx-k, respectively, and the new sample standard deviation is OC When a constant k is added to or subtracted from each entry, the new sample mean is x +kor -k, respectively, and the sample standard deviation remains A. ов. sok sk D. unaffected.
