For the remaining 7 seats, the number of ways in which the people can sit is an arrangement of 7 elements. So

T = 4*7! = 4*5040 = 20160

Mean = all numbers added up ÷ amount of numbers So 22 + 24 + 26 + 20 + 29 + 28 + 26 = 175 175 ÷ 7 = 25 for mean Median = middle number when arranged in order 20, 22, 24, 26, 26, 28, 29. Middle number is 26. Mode = most frequent number Also 26 because it appears twice whereas all the other numbers only appear once. Range = highest number - lowest number 29 - 20 = 9.
