Question

Suppose the transit system of a large city has a lost and found department that keeps detailed records, including the estimated value in dollars of each lost item. Each year the department publishes a report with a histogram showing the proportion of items lost in various price ranges.

The bar on the histogram with endpoints 100 to 200 has a height of 0.11. What does this mean?

(A) of the lost items, 11% cost $150.
(B) Between 100 and 200 items had an estimated value of 11% of the total cost of all items.
(C) Of the lost items, 11% cost between $100 and $200.
(D) It is impossible to answer the question because it does not say what variable is displayed on the horizontal axis.
(E) Of the lost items, 11% had an average cost of $150.

Answer 1

(C) Of the lost items, 11% cost between $100 and $200

On the Y-axis is represented the frequency of lost items found.

In this case in the form of a percentage.

On the X-axis is represented the range of prices

See picture attached.

So, this means that 11% of the found items have an estimated price between $100 and $200
