Rs. 10000, Rs. .10250, Rs. .10790, Rs. .9865, Rs. .15350, Rs. .10110

Answer :

Given, observations 10000, 10250, 10790, 9865, 15350, 10110

Clearly, No of observations, n = 6

We know,

Arithmetic mean of x_{1}, x_{2}, x_{3}, …, x_{n} (n observations) is

Therefore, mean of above data

Hence, mean is Rs. 110060.83
