The following data gives the information on the observed lifetimes (in hours) of \(225\) electrical components :
| Lifetimes (in hours) | \(0-20\) | \(20-40\) | \(40-60\) | \(60-80\) | \(80-100\) | \(100-120\) |
| Frequency | 9 | 33 | 52 | 60 | 37 | 26 |
Determine the modal lifetimes of the components.
Mode \(=\) _________.
