    Answer:

    Step-by-step explanation:

    From the information given:

    We can compute the required calculations into a table as shown below.

    \mathbf{Data \ value }       \mathbf{ Frequency } \mathbf{Relative \ frequency}   \mathbf{Cumulative \ relative }

                                                                                                  \mathbf{Frequency}

    5                                     14                14/65 = 0.22                           14  

    6                                     19                19/65 = 0.29               19+14 = 33

    7                                      12                12/65 = 0.19               33+12 = 45

    8                                       9                 9/65 = 0.14               45 + 9 = 54

    9                                     11                11/65  = 0.17              54 + 11 = 65

                                            65

    Note: that the relative frequency is determined by  dividing each value in the frequency by the total of the frequency.
