1 For sample values x X X the sample variance is s n 1 a Show that the sample variance is unchanged if a constant c is added to or subtracted from each value in the sample b Show that the sample variance becomes c times its original value if each observation in the sample is multiplied by c Each x a If a constant c is added to or subtracted from each value in the sample how do the sample values x change becomes X C n 1 x x where x x is the sample mean n i 1 i 1 becomes cx remains unchanged TE
