Answer 2

Step-by-step explanation:

Family size Number of families 1−3 7=f03−58=f15−72=f27−929−111  ∑f=20Mode =l+2f1−f0−f2f1−f0×h

Whereas,

l= Lower limit of modal class =3

h= Class interval =5−3=2

f0= frequency of class preceeding the modal class =7

f1= frequency of modal class =8

f2= frequancy of class succeding the modal class =2

Therefore,

Mode =3+(2×8)−7−28−7×2=3+16−91×2=3+72=3.286

Hence the mode of the given data is 3
