1. X and Yare two independent measurements. X = 10 +1 and Y = 30 ± 2, where 10 and 30 are the means of the measurements X and Y, respectively. Also, 1 and 2 are the standard deviation (uncertainty) associated with the measurements X and Y, respectively. Thus, these measurements can be treated as independent random variables. Find the mean, variance, and standard deviation of the following combinations. a) Z, = 2X + 2Y b) Z2 = X – 3Y +1
