During a particular week in the first trimester, a tutor recorded, to the nearest hour, the time spent watching online movies by each student in a random sample. The times were summarized in a grouped frequency table and represented by a histogram. One of the classes in the grouped frequency distribution was 3-4 and its associated frequency was 9. On the histogram, the height of the rectangle representing that class was 3.6 cm and the width was 2 cm. (a) (b) Give a reason to support the use of a histogram to represent the data. State the relationship between the area of the bars in a histogram and the frequency. FHMM1034 Mathematics III – Tutorial 1 (c) Show that on this histogram, each student was represented by 0.8 cm?. 3. 6.
