Answer:

Z=L1+(F1-F0)/(2F1-F0-F2)*i

Step-by-step explanation:

L1 = lower limit of modal class F1 = modal class frequency. F2 = just after the modal class frequency. F0 = just previous the modal class frequency.

Answer 2

Step-by-step explanation:

The Modal group is the one with the highest frequency, which is 20 - 29: L = 20 (the lower class boundary of the modal class) fm-1 = 21.
