Question

part 3: what went wrong? the economic research service (ers) from the united states department of agriculture (usda) uses information from different retail establishments to provide estimates of the average price per pound (in dollars) of different fruits and vegetables. these prices are used when publishing the dietary guidelines for americans in order to show individuals how much it will cost them to maintain a healthy diet. the graph below shows the distribution of the estimated average prices per pound, in 2024, of a sample of fruits. questions 11 through 13 each given an incorrect interpretation of the information shared in this graphical display. explain what is wrong with each incorrect interpretation. 11. because there are 9 bars in this graph, this means the data set includes only 9 fruits.

Explanation:

The bars in a histogram represent intervals of data (price - ranges in this case), not individual data - points (fruits). Each bar's frequency is the number of fruits whose average price per pound falls within that price - range. So, the number of bars does not equal the number of fruits in the data set.

Answer:

The error is that the number of bars in the histogram is misinterpreted as the number of fruits. The bars represent price intervals, and the frequency of each bar is the number of fruits within that price - range.
