Water-level in a tank measured at ten locations, i=1,2,,10 refers to random depths, di (in meters) denoting the RV. The number of measurements conducted at each location is denoted by, 7. The bottom surface of the lake has a profile such that the measured depths at each location is influenced by neighboring site sequenced as i=1 to 10 . Determine the following with reference to the RV indicated: (a) Appropriate average performance measure of the RV set (ii) Median value of depth variation 3.363.601.922.16.5.166.36
