The following shows the waiting time, \(x\) minutes, at a clinic for \(30\) patients to see the doctor.
| \(3\) | \(48\) | \(27\) | \(17\) | \(31\) | \(38\) | \(8\) | \(50\) | \(16\) | \(48\) |
|---|---|---|---|---|---|---|---|---|---|
| \(18\) | \(41\) | \(41\) | \(4\) | \(35\) | \(43\) | \(15\) | \(44\) | \(30\) | \(17\) |
| \(47\) | \(37\) | \(28\) | \(27\) | \(10\) | \(20\) | \(51\) | \(57\) | \(8\) | \(58\) |
