JEE Advanced 2023 Mathematics question
Consider the given data with frequency distribution : 3, 8, 11, 10, 5, 4 : 5, 2, 3, 2, 4, 4 Match each entry in List-I to the correct entries in List-II. List-I (P) The mean of the above data is (Q) The median of the above data is (R) The mean deviation about the mean of the above data is (S) The mean deviation about the median of the above data is List-II (1) 2.5 (2) 5 (3) 6 (4) 2.7 (5) 2.4 The correct option is:
Answer: (A)
Solution
, , mean (P → 3). In ascending order the cumulative frequencies are 3:5, 4:9, 5:13, 8:15, 10:17, 11:20; the 10th and 11th values
