Assertion (A): A survey was conducted by a group of student as a part of their environment awareness program in which they collected the following data regarding the number of plants in 10 houses in a locality. Number of plants | Number of houses -------------| --------------- 2 - 4 | 2 4 - 6 | 3 6 - 8 | 1 8 - 10 | 3 10 - 12 | 1 The mean of the data is 6.9. Reason (R): If the observation x1, x2, x3,........., xk has frequencies f1, f2, f3, ........, fk, then mean = 1. Assertion (A) is true, but Reason (R) is false. 2. Assertion (A) is false, but Reason (R) is true. 3. Both Assertion (A) and Reason (R) are correct, and Reason (R) is the correct reason for Assertion (A). 4. Both Assertion (A) and Reason (R) are correct, and Reason (R) is incorrect reason for Assertion (A).
