Answer
The first 5 odd natural numbers are: 1, 3, 5, 7, 9.
The mean (arithmetic average) is calculated as the sum of all observations divided by the number of observations.
Sum = 1 + 3 + 5 + 7 + 9 = 25
Number of observations = 5
Mean = = 5
∴ Assertion (A) is true.
The mean is the arithmetic average (sum of values divided by the count).
The median is the middle value of a set of observations when they are arranged in ascending or descending order.
∴ Reason (R) is false.
∴ Assertion (A) is true, Reason (R) is false.
Hence, option 1 is the correct option.
