1. **Stating the problem:** We are given a tally and frequency table for shirt colors. The tally for "Plain" shirts is missing, and the frequency number for "Plain" shirts is also missing. We need to draw the tally for "Plain" shirts and find the missing frequency number. 2. **Understanding tally marks:** Each tally mark represents 1 item. A group of 5 is usually shown as four vertical lines with a diagonal line crossing them, representing 5. 3. **Given data:** - Stripy shirts have a frequency of 7, which means 7 tally marks. - Plain shirts tally and frequency are missing. 4. **Assuming the total number of shirts or additional data is missing, we cannot find the exact number for Plain shirts.** 5. **If the total number of shirts or the frequency for Plain shirts was given, we could subtract the known frequency (7 for Stripy) from the total to find the Plain frequency.** 6. **Drawing tally for Plain shirts:** If the frequency for Plain shirts is $n$, then the tally would have $n$ marks, grouped in fives. Since the problem does not provide the total or the frequency for Plain shirts, we cannot determine the missing number or draw the tally accurately. **Final answer:** More information is needed to find the missing frequency and draw the tally for Plain shirts.
