Question

Construct the cumulative frequency distribution for the given data. Daily Low ​(degrees°​F) Frequency ​35-39 11 ​ 40-44 22 ​ 45-49 44 ​ 50-54 13 55-59 66 ​ 60-64 88 ​ 65-69 11 Construct the cumulative frequency distribution.

Answer 1

Answer:

The cumulative  frequency distribution is

Class      Cumulative

Interval  frequency      

35-39 11

40-44 33

45-49 77

50-54 90

55-59 156

60-64 244

65-69 255

Step-by-step explanation:

Class

Interval  F  C.F      

35-39 11 11

40-44 22 11+22=33

45-49 44 33+44=77

50-54 13 77+13=90

55-59 66 90+66=156

60-64 88 156+88=244

65-69 11 244+11=255

The first column contains class interval. The second column denoted by F contains frequencies. The third column contains cumulative frequencies denoted as C.F.
