Show answer & explanation

Correct answer: C. A-III, B-IV, C-I, D-II

Explanation

Area within ±1 SD ≈ 0.68 (A-III). From −1 to +2 ≈ 0.34 + 0.475 ≈ 0.82 (B-IV). Everything below the mean = 0.5 (C-I). Below −1 = 0.5 − 0.34 ≈ 0.16 (D-II). So A-III, B-IV, C-I, D-II.±1 SD के भीतर क्षेत्रफल ≈ 0.68 (A-III)। −1 से +2 तक ≈ 0.34 + 0.475 ≈ 0.82 (B-IV)। माध्य से नीचे पूरा क्षेत्र = 0.5 (C-I)। −1 से नीचे = 0.5 − 0.34 ≈ 0.16 (D-II)। अतः A-III, B-IV, C-I, D-II।
