18th number in the sequence of hours (increasing) is the median. From the given frequency distribution, the 18th number, which is the median is 6

total emplyoees= 35
median emplyoee= (35+1)/2 = 18th emplyoee.
median hour spent is the median emplyoee's hours spent=6 hours.

3 5 8 8 9 48 70

8 looks like the median...

Median = [(n+1)/2]th value = [(35+1)/2]th value= 18th value, which is 6 hours.

Does the formula work for even N numbers too?

For even numbers you need to take average of the 2 middle numbers as median.
