5. the overall shape for this graph is
6. what percent of the total students who participated in the sale sold 21 - 25 candy bars?
7. points scored - basketball team november
8. how many players scored points in november?
9. what percent of the total player scored 31 - 40 points in november?

Explanation:

Step1: Find total number of students

Add the number of students in each interval: \(4 + 6+6 + 8+12=36\)

Step2: Calculate percentage for \(21 - 25\) interval

The number of students in \(21 - 25\) interval is \(12\). Use the formula \(\text{Percentage}=\frac{\text{Part}}{\text{Whole}}\times100\). So \(\frac{12}{36}\times100=\frac{1}{3}\times100\approx33.3\%\)

Answer:

\(33.3\%\)
