We get the cumulative frequency as:

                3

                7

               13

               22

               29

               36

               37

We are given the data:

Daily Low(°F)    Frequency

 35 - 39                    3

 40 - 44                    4

 45 - 49                    6

 50 - 54                    9  

 55 - 59                    7

 60 - 64                    7

 65 - 69                     1

We have to find the cumulative frequency of the data.

We will do this by adding the data values of previous interval.

Daily Low(°F)    Frequency     cumulative frequency

 35 - 39                    3                              3

 40 - 44                    4                              7

 45 - 49                    6                             13

 50 - 54                    9                             22

 55 - 59                    7                             29

 60 - 64                    7                             36

 65 - 69                    1                              37

Therefore, we get the cumulative frequency as:

                3

                7

               13

               22

               29

               36

               37
