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 | \(10\) | \(35\) | \(52\) | \(61\) | \(38\) | \(29\) |
Determine the modal lifetimes of the components.
Answer:
Mode \(=\)
[Note: Enter the answer upto \(2\) decimals.]
