Answer and Step-by-step explanation:
The calculation of cumulative frequency distribution is shown below:-
Daily low temperature Frequency cumulative frequency
35-39 3 3
40-44 2 3 + 2 = 5
45-49 5 5 + 5 = 25
50-54 12 25 + 12 = 37
65-69 6 37 + 6 = 43
55-59 8 43 + 8 = 51
60-64 1 51 + 1 = 52
We simply applied the above format
