Follow-up Question

Can you please show the cells how got frequency, relative frequency and cumulative frequency

4
Start with the minimum value as the lowest limit of the first class. Add 4 to it to obtain the upper
limit of the first class i.e., 116. Start with the next value 117 as the lower limit of the second class,
add 4 to obtain the upper limit. Repeat the same for the remaining classes.
The frequency distribution of the data is:
