### Frequency Table of Study HoursConsider the following frequency table representing the distribution of hours students study for an exam in a week.| **Hours Students Study for an Exam in a Week** | | ||------------------------------------------------|-------|------------|| **Class** | **Frequency** || 10–18 | 8 || 19–27 | 11 || 28–36 | 7 || 37–45 | 4 || 46–54 | 3 |Determine the class width of each class.### Explanation- **Class**: The range of study hours.- **Frequency**: The number of students falling into each range.### TaskCalculate the class width, which is the difference between the upper and lower boundaries of each class interval. For example, for the interval 10–18, the class width is \(18 - 10 + 1 = 9\).

Please do not give solution in image format thanku A car salesman collected data on how many cars were sold at a dealership per day for two weeks. The results were as follows: 6, 7, 4, 3, 1, 2, 6, 6, 6, 7, 4, 4. Make a frequency table and then make a histogram based on that frequency table. What is the shape of the distribution?

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…
