Step-by-step explanation:
Given The numbers 1, 1, 3, x, 6, 6, 7 are arranged in ascending order. If their mean and median is same, find the value of x.
- So given data in ascending order 1,1,3,x,6,6,7
- Now total number of observations = N = 7 (odd)
- Therefore Median = (N + ½)th observation
- = 7 + 1 / 2
- = 8/2
- = 4th term
- = x
- Now Mean = 1 + 1 + 3 + x + 6 + 6 + 7 / 7
- = 24 + x / 7
- According to the question
- Median = Mean
- x = 24 + x / 7
- 7 x = 24 + x
- 7x – x = 24
- 6x = 24
- x = 24 / 6
- x = 4
