Question

Consider the following distribution of daily wages of 50 workers of a factory?

Answer 1

Answer:

Let’s find mean of the data using assumed mean method.

We are using assumed mean method to avoid miscalculation and false answer, as xi's are large in this question.

First, construct a table for ease of calculation.

Mean is given by

Where A = assumed mean

 Mean = 325 – 12 = 313

Thus, mean daily wages of the workers is Rs. 313.
