Question

Answer is 69.43
How??
(Assumed mean method)​

Answer 1

Answer:

Step-by-step explanation:

Mean = a + h * (∑FiUi)/∑Fi

Where a = assumed Mean = 70

h = Class Interval = 55 - 45 = 10

From the table we can see that

∑Fi = 35,  and ∑FiUi = -2

So Mean = 70 + 10 * -2/35

               = 70 - 4/7 = 70 - 0.57 = 69.43 (Approx. )

Thus mean literacy rate = 69.43%.
