1.If both the mean and the standard deviation of 50 observations x1,x2,…,x50x_1, x_2, \ldots, x_{50}x1,x2,…,x50 are equal to 16, then the mean of (x1−4)2,(x2−4)2,…,(x50−4)2(x_1-4)^2, (x_2-4)^2, \ldots, (x_{50}-4)^2(x1−4)2,(x2−4)2,…,(x50−4)2 isa.525b.480c.400d.380Login to continueOnly logged in users canattempt or see the solution.
