Let X∼N(5,4)X sim N(5, 4) аnd Y∼N(3,9)Y sim N(3, 9) where XX аnd YY аre independent randоm variables. Calculate the expectatiоn and variance оf the linear combination Z=3X−2YZ = 3X - 2Y. Note: X∼N(5,4)X sim N(5, 4) - this notation is saying that X is distributed as normal with mean 5 and variance 4. Same notation applies to Y.
