Question

Explanation:

Step1: Analyze the histogram

The histogram has intervals \(0 - 3\), \(3 - 6\), \(6 - 9\), \(9 - 12\), \(12 - 15\). The frequency of \(9 - 12\) is \(4\) and the frequency of \(12 - 15\) is \(1\).

Step2: Calculate the number of students

Since "at least 9 minutes" includes the intervals \(9 - 12\) and \(12 - 15\). We add their frequencies. So \(4+1 = 5\).

Answer:

\(5\)
