To determine Construct a relative frequency distribution for the 2,000 cars with a class width of 2, where the first class has a lower limit of 15. Explanation Calculation: The given information is that a data representing the mileage in miles per gallon for 2,000 and 2,013. Frequency: The frequencies are calculated by using the tally mark and the range of the data is from 15 to 40.9. Based on the given information, the class intervals are 15.0-16.9, 17.0-18.9, 19.0-20.9, 21.0-22.9, 23.0-24.9, 25.0-26.9, 27.0-28.9, 29.0-30.9, 31.0-32.9, 33.0-34.9, 35.0-36.9, 37.0-38.9 and 39.0-40.9. Make a tally mark for each value in the corresponding mileage class and continue for all values in the data. The number of tally marks in each class represents the frequency, f of that class. Similarly, the frequency of remaining classes for the mileage is given below: Mileage Tally Frequency 15.0-16.9 | 1 17.0-18.9 0 19.0-20.9 0 21.0-22.9 | | | 3 23.0-24.9 | | | | | 6 25.0-26.9 | | | 3 27.0-28.9 | | | | | | | | | | | | | | 17 29.0-30.9 | | | | | | | | 9 31.0-32.9 | | | | | | | | 9 33.0-34.9 | | | | | | 7 35.0-36.9 | | 2 37.0-38.9 | | | | 4 39.0-40.9 | | 1 Total 62 Relative frequency: The general formula for the relative frequency is, Relative Frequency = Frequency Total frequency Therefore, Relative Frequency for the class 15
