Question

The mean and variance of x are 50 and 4 respecitely. Estimate mean of x^2. The variance and standard deviation of 2x+3

Answer 1

Step-by-step explanation:

Mean, Variance and Standard Deviation. single die ... 1, 2, 3, 4, 5, 6 ... When we know the probability p of every value x we can calculate the Expected Value (Mean) of X: μ = Σxp ... 0.4, 50, 20, 1000.
