Question

Which of these is not a valid reason for arguing that there is a lesser
possibility of famine in a democratic country?​

Answer 1

Answer:

Class mark = 9.5

=> Upper limit + Lower limit / 2 = 9.5

=> u + l = 19 -------(1)

Class mark = 6

=> u - l = 6 --------(2)

On adding equation 1 and 2, we get

2u = 25

=> u = 12.5

l = 6.5

Class interval is ( 6.5 - 12.5)
