1) The number of eggs measured is found by adding the frequencies.

So, number of eggs measured = 1 + 8 + 17 + 40 + 26 + 8 = 100

2) The number of eggs less than or equal to 23 mm in length is found by adding the frequencies for the groups 19-20, 20-21, 21-22 and 22-23.

Required number of eggs = 1 + 8 + 17 + 40 = 66
