### Constructing Expanded Frequency Distribution#### Initial Frequency Distribution for High Temperatures (°F):| Class | 17-27 | 28-38 | 39-49 | 50-60 | 61-71 | 72-82 | 83-93 ||---------|-------|-------|-------|-------|-------|-------|-------|| Frequency, f | 18 | 43 | 66 | 67 | 79 | 66 | 26 |#### Complete the Table Below for High Temperatures (°F):(Round to the nearest hundredth as needed.)| Class | Frequency, f | Midpoint | Relative frequency | Cumulative frequency ||---------|---------------|----------|--------------------|----------------------|| 17-27 | 18 | | | || 28-38 | 43 | | | || 39-49 | 66 | | | || 50-60 | 67 | | | || 61-71 | 79 | | | || 72-82 | 66 | | | || 83-93 | 26 | | | |### Explanation:- **Class**: The range of high temperatures.- **Frequency, f**: The number of occurrences within each class.- **Midpoint**: The central value of each class range.- **Relative frequency**: The proportion of the total frequency represented by each class.- **Cumulative frequency**: The sum of frequencies for the current class and all previous classes.To complete the table:1. **Midpoint calculation**: For each class, calculate the midpoint by averaging the lower and upper boundaries. For example, for the class 17-27, the midpoint is `(17+27)/2 = 22`.2. **Relative frequency calculation**: Divide the frequency of each class by the total frequency. Suppose the total frequency is `365`. The relative frequency for the class 17-27 is `18/365 = 0.05` (rounded to the nearest cent).3. **Cumulative frequency calculation**: Add the current class frequency to the sum of all previous class frequencies. For the first class, it remains the same

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…
