Continuing from Problem 3.44, using Minitab and the file “Recycling_Diversion_and_Capture_Rates”:
a) Construct a histogram for diversion rates, fiscal year 2018, in New York City.
b) Modify the histogram to look like Figure 3.6.

Problem 3.44

When constructing histograms, the statistical software being used will commonly determine how the graph looks. In Example 3.2, histograms were developed to summarize diversion rates in New York City (Figure 3.6). The required steps and output to get a histogram summarizing the same data using Minitab can be found in Figure 3.24. Why does the resulting histogram have a different shape than the ones seen in Figure 3.6?

Example 3.2

Figure 3.6 presents a histogram of 2018 recycling diversion rates (total recycling / total waste × 100) for several New York City zones8 in terms of frequencies (left) and relative frequencies (right).
