Answer:

56.6

Step-by-step explanation:

CI                          f                      cf

40-45                   2                     2

45-50                   3                     5

50-55                   8                     13

55-60                   6                     19

60-65                   6                     25

65-70                    3                     28

70-75                     2                    30

∴ n = 30, then (n/2) = 15.

55 - 60 is the median class.

Here, l = 55, cf = 13, f = 6, h = 5

(i)

Let x = (n/2 - cf)

        = (15 - 13)

        = 2

(ii)

Median = l + (x/f) * h

             = 55 + (2/6) * 5

             = 55 + (10/6)

             = 56.6

Therefore, median = 56.6

Hope it helps!
