<PRE><B>Question 1048212</B>
Relative Frequency Table for a Quantitative Variable:

A gas station manager recorded the amount of gasoline car owners bought during a one hour time period on a Friday afternoon. The frequency distribution below shows the distribution for amount of gasoline (in gallons) purchased:


Amount of Gasoline(0.0-2.9)        Frequency( 2)       Relative Frequency (0)
(in Gallons)
                     
Amount of Gasoline (3.0-5.9)        Frequency( 8)     Relative Frequency (0.40)
          
Amount of Gasoline (6.0-8.9)        Frequency(3)      Relative Frequency (.15)

Amount of Gasoline (9.0-11.9)      Frequency (5)     Relative Frequency (0.25)
  
Amount of Gasoline (12.0-14.9)     Frequency (4)     Relative Frequency (0.20)   

Total 20  

1. Complete the above table, with frequencies and relative frequencies:

2. What percentage of gasoline purchases were at least 9 gallons? Please show how you obtain the answer
5 that were (9-11.9)
4 that were (12-14.9(
---
Percentage = 9/20 = 45%
