In Solution C, Histogram: boundaries at 9,34 and 44 with frequency densities of 98 and 15. How did we get the boundaries at 9,34, and 44? Can you please show me the solution on how to create this histogram and the table of classes with the given solution.

Last year Tom renovated an old building during which he worked for at least 9 hours each week. By plotting four points in a graph, he has represented the time he spent working. cf (No. weeks) 34. 36 38 4006 042 4h Time spent working (hours) a What can you say about the time that Tom spent working on the basis of this graph? b Explain why Tom's graph might be considered to be misleading. c Name the different types of representation that are suitable for displaying the amount of time that Tom worked each week throughout the year. Consider the benefits of each type of representation and then fully describe (but do not draw) the one you believe to be the most suitable. a For example, he worked for less than 34 hours in 49 weeks, and for more than 34 hours in three weeks. b It may appear that Tom worked for more than 34 hours in a significant number of weeks. c Histogram: boundaries at 9,34 and 44 with frequency densities of 98 and 15. Pie chart: sector angles ~ 339.2 and 20.8". Bar chart: frequencies 49 and 3. Sectional percentage bar chart: + 94.2% and 5.8%
