Use the tally chart (table) to draw a concrete graph. (Note: use square [ ] to represent colour.)

Here's how to complete the tally chart and draw the concrete graph: Step 1: Complete the tally chart Using the given data, fill in the missing tally marks and numbers. Red: Tally HHH HH I represents 5 + 5 + 1 = 11 pupils. Yellow: 8 pupils are represented by HHH III. Green: Tally HHH IIII represents 5 + 4 = 9 pupils. Blue: 6 pupils are represented by HHH I. The completed tally chart is: | Favourite Colour | Tally | Number of pupils | | :--------------- | :---------------- | :--------------- | | Red | HHH HH I | 11 | | Yellow | HHH III | 8 | | Green | HHH IIII | 9 | | Blue | HHH I | 6 | Step 2: Draw the concrete graph The problem states to use a square () to represent each pupil. We will draw the corresponding number of squares for each colour. The concrete graph is: Red: Yellow: Green: Blue: Here is the final answer for both parts: Completed Tally Chart: |l|l|l| Favourite Colour & Tally & Number of pupils \\ Red & HHH HH I & 11 \\ Yellow & HHH III & 8 \\ Green & HHH IIII & 9 \\ Blue & HHH I & 6 \\ Concrete Graph: l Red: \\ Yellow: \\ Green: \\ Blue: Drop the next question!
