Problem 5 (20pt) 1. Let Cl = A sin@t + O) + b, where A has mean a and variance o , and w, e, 1, and b are constants. Find the mean and variance of Cl _ 2. Let C2 = A sin@t + B) + b, with a uniform random variable in the interval O and 2m, and w, A, t, and b are constants. Find the mean of Ch. hint: use properties of expectation and variance.
