Solution :-

Class interval Fi Xi FiXi

0 - 10 5 5 25

10 - 20 8 15 120

20 - 30 12 25 300

30 - 40 6 35 210

40 - 50 9 45 405

50 - 60 10 55 550

Total Fi = 50 Fixi = 1610.

we know that,

  • Mean = ⅀Fixi / ⅀Fi .

Putting value we get,

→ Mean = 1610 / 50

→ Mean = 161 / 5

→ Mean = 32.2 .(Ans.)

Hence, Mean of the given data is 32.2.
