1. Consider n = 8 values denoted 2:1, 2:2, 2:3, 2:4, 2:5, 2:6, 2:7, 2:3. Throughout this question let _ 1 8 3: gm.- i=1 00 | denote the average of these values. For this question, you need to match the expression in the lefthand column below with the equivalent expression in the right-hand column. For convenience, the expressions on the left are labeled with numbers (e. g. Expression 1, Expression 2, . . .) and the expressions on the right with letters (eg. Expression A, Ebcpression B, . . .) 8 Expression 1: Z 2215 Expression A: 2(E + 1) i=1 8 Expression 2: 261:; 8) Expression B: 2 (E 1) i=1 8 Expression 3: 2 mi 8 Expression C: SE i=1 3 . 1 . _ Express10n 4: a Z (2:.- + 1) Expression D: 8 (:1: 1) i=1 3 . 1 . _ Express10n 5: 2 2 g (3,; 1) Expression E: 8 (a: 8) i=1 To make your answer clear, you are advised to use a format of answer similar to that below. Simply replace the ............... with the name of the correct matching expression from the right-hand column. Expression 1 = ............... Expression 2 = ...............
