The resulting sample values are tabulated below. x (i) x (i) x (i) 0.19 -1.24 14 1.45 0.29 -1.88 15 .0.82 1.44 -0.31 16 -0.25 0.83 1.18 17 0.23 -0.01 1.70 18 -0.91 -1.23 0.57 19 -0.19 -1.47 13 0.95 20 0.24 a) Estimate the mean value of this process. b) If the process has a true variance of 1.0, find the variance of your estimate of the mean
