1) The environmental Protection Agency (EPA) performed extensive tests on all new car models to determine their mileage ratings. Suppose that the 40 measurements below represent the results of such tests. How can we summarize the information in this rather large sample? 35 39 40 46 45 41 30 32 42 38 42 25 33 28 41 37 33 28 33 32 31 35 38 35 30 34 39 40 27 33 41 36 42 41 35 45 37 29 40 37 To organize the data follow the instructions to construct a frequency table and draw a frequency histogram or a relative frequency histogram. 1) Use six classes to determine the class width 2) Determine the class limits and class boundaries 3) For each value draw a tally mark 4) Count the tallies to find the class' frequencies 5) Determine the relative frequencies 6) Determine the mid-point for each class Class Limits Class Boundaries Tallies Frequency Relative Class Lower-Upper Lower - Upper Frequency Mid-Points Totals
