(a) Explanation Given: Mr Abramovich had $5.7 billion and 80,000 other residents of Chukotka were poor. Definition used: Formula for finding the mean for grouped data: Let x ¯ be the mean and it is denoted as, x ¯ = ∑ f x n , where f is frequency, x is midpoint and n is the sum of the frequencies, where n = ∑ f . Calculation: Calculate the average worth if the other 80,000 residents of Chukotka worth $100. It is given that x 1 = 5 , 700 , 000 , 000 , x 2 = 100 , f 1 = 1 , f 2 = 80 , 000 and n = f 1 + f 2 (b) To determine To explain: The use of the mean to describe an average.
