The following table shows the number of children in each house of a society.Number of ChildrenNumber of Houses0611721733What is the average number of children per house?

Solution & Step-by-step Explanation

To find the average number of children per house, we use the weighted mean formula: Average = \frac{\sum ( f \times x )}{\sum f} Where: x = Number of children f = Number of houses \sum f = 6 + 17 + 17 + 3 = 43 Now compute \sum (f \times x) : (0 \times 6) + (1 \times 17) + (2 \times 17) + (3 \times 3) = 0 + 17 + 34 + 9 = 60 Average = \frac{60}{43} \approx 1.395 \approx 1.4
