Calculate the covariance across the following two series of returns, as well as the variance of each individual series. These series constitute the entire population of observations. Series A: 0.08,0.02,0.03, and -0.02 . Series B:0.05,0.06,0.07, and -0.08 . Note that A 's average return is 0.0125 and B 's average return is -0.0050
