The following data represents the average time spent, in hours, on homework in a week of \(25\) students.
\(4\) | \(9\) | \(7\) | \(8\) | \(5\) |
|---|---|---|---|---|
\(8\) | \(6\) | \(6\) | \(5\) | \(4\) |
\(11\) | \(10\) | \(5\) | \(8\) | \(12\) |
\(5\) | \(8\) | \(9\) | \(9\) | \(11\) |
\(7\) | \(7\) | \(11\) | \(10\) | \(5\) |
