Question # VII Two electric service utilities (ESUS), X and Y have charged their service areas country- wide at competitive tariff-rates (expressed in $) that change randomly over ten years, 2009-2018 (indexed as r=1 through 10 for X and Y) as summarized below in the table. Relevant tariff-rates (TX) and (T) shown depict RVs having corresponding frequencies of occurrence, (n.), and (n), respectively. Hence, determine the following: (1) Statistical divergence between the sample-spaces of the RVs in X and Y expressed in terms of Kullback-Leibler (KL) measures, KL1 and KL2. (2) Plot year-by-year profiles of KLI versus) and (T, KL2 versus r) and comment on the differences observed (3) Infer the stretch of time (in years) in which both X and Y perform almost closely in terms of their tariffs (4) Find Pearson-1 and 2 skewness coefficients between sample-spaces of RVs of X and Y (5) Suppose successive annual tariffs grow (or decline) in X and Y depending on previous year rate, decide the appropriate average performance in each case of X and Y in terms of AM or HM or GM.
