### Frequency Distribution Table Construction for Screw Lengths**Instructions:**Refer to the accompanying data set and use the 30 screw lengths to construct a frequency distribution. Begin with a lower class limit of 3.970 inches, and use a class width of 0.010 inches. The screws were labeled as having a length of 4 inches.**Data:**The data table provided contains the following screw lengths (in inches):```4.002, 4.007, 4.003, 4.002, 3.982, 3.993, 3.995, 3.974, 4.009, 4.001,4.003, 3.995, 3.996, 3.987, 3.995, 4.007, 3.999, 3.998, 3.993, 4.014,3.996, 4.015, 4.008, 4.002, 3.995, 3.983, 4.001, 4.001, 4.008, 3.991```**Frequency Distribution Table:**```Complete the frequency distribution below.Length (in.) Frequency3.970 - 3.979 [ ]3.980 - 3.989 [ ]3.990 - 3.999 [ ]4.000 - 4.009 [ ]4.010 - 4.019 [ ]```**Step-by-Step Explanation:**1. **Determine Class Intervals:** - Start from 3.970 inches. - Add class width 0.010 inches to each subsequent class: - First class: 3.970 - 3.979 - Second class: 3.980 - 3.989 - Third class: 3.990 - 3.999 - Fourth class: 4.000 - 4.009 - Fifth class: 4.010 - 4.0192. **Tally the Data:** - Count the number of screw lengths that fall within each class interval. - Enter these counts in the frequency column.**Graphical Representation:**Normally, a histogram or bar graph would be created to visually represent the frequency distribution. Each bar would represent a

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…
