Recall that a relative frequency histogram is used to graph quantitative data. Classes are chosen to divide the range of values into equal-length subintervals, then plotted along the horizontal axis. A bar is drawn for each class with height equal to the relative frequency for that class. To create a relative frequency histogram, first summarize the following data in a frequency table. 1 N 2 3 4 5 6 7 Class Class Boundaries 8 9 1.3 10 11 14.7 9.0 16.7 4.1 14.9 4.4 2.7 32.3 10.9 9.0 9.0 1.6 18.4 1.0 2.4 2.4 18.0 Since the measurements are all between the values 0 and 33, it will be convenient to choose 11 class intervals of length 3. Using the given data, tally the values within each class interval to determine the frequency of each class, and fill in the following table. 0 to <3 3.5 11.2 18.0 26.7 3.7 3 to 6 6 to 9 9 to 12 12 to < 15 15 to 18 18 to 21 21 to 24 24 to 27 0.2 6.1 13.5 27 to < 30 30 to 33 7.4 8.2 19.2 1 1 2 1 Frequency 10 5 1 4 1 X X 9.4 X 8.7 X 2.0 6.6 3.9 5.9 4.3 3.3 0.2…

Daily High Temp. The histograms describe the high temperatures in a certain city on each day of one month. The histogram on the left uses class widths of 3°F and the histogram on the right uses class widths of 6°F. Assume that temperature is measured and recorded as whole number values so that the first class would be 64°F-66°F when using a class width of 3°F. Complete parts (a) through (c) below. Daily High Temp. 64 70 76 82 88 94 Degrees Farenheit 64 70 76 82 88 94 Degrees Fareniheit a. During this month, there tends to be two types of weather. The city experiences either cool, foggy days or hot, sunny days. Which of the two histograms better reflects this? O A. The histogram with class widths of 6°F, because the histogram has larger class widths. O B. The histogram with class widths of 6°F, because there are no gaps in the histogram. OC. The histogram with class widths of 3°F, because the two distinct groups of data are separated by a gap in the histogram. O D. The histogram with…
