Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week. Fourteen people answered that they generally sell five cars; nineteen generally sell six cars; twelve generally sell seven cars; nine generally sell eight cars; eleven generally sell nine cars. Calculate the following. (Round your answer to two decimal places.)Data Value (# cars) Frequency Relative Frequency Cumulative Relative Frequency

Answer:

Step-by-step explanation:

From the information given:

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

[tex]\mathbf{Data \ value }[/tex]       [tex]\mathbf{ Frequency }[/tex] [tex]\mathbf{Relative \ frequency}[/tex]   [tex]\mathbf{Cumulative \ relative }[/tex]

                                                                                              [tex]\mathbf{Frequency}[/tex]

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.
