Question

A state’s legislature was considering the funding of it's parks system. As part of the considerations, a study was done to look at the number of unique visitors to a section of the states parks over the memorial day weekend. The histogram below summarizes the data. Use the histogram to answer each of the question

Answer 1

a) To determine the number of parks from 270 to 419, notice that the height of the second bar of the graph give us this information. The answer is:

Number of parks from 270 to 419 = 4

b) The total number of parks is given by the sum of the heights of all bars (due to the height of the bar represents the number of parks). Then, you have:

Total number of parks = 9 + 4 + 6 + 3 + 9 = 31

Hence, there are 31 parks

c) Consider that the class width refers to the difference between the upper and lower limits of a class. In this case, you can notice that the difference beween the limits is 150 (for example 419 - 270 = 150)
