Solution

The correct option is A
In statistics, 'the assumed mean' is a method for calculating the arithmetic mean and standard deviation of a data set. It simplifies calculating accurate values by hand.

During the application of the short-cut method for finding the mean, the deviation d, are divisible by a common number ‘h’. In this case, the di = xi – A is reduced to a great extent as 'di' becomes $\frac{d i}{h}$ . In this method, we divide the deviations by the same number to simplify calculations. The deviation is $d_{i} = x_{i} - A$
