A researcher conducts a mileage economy test involving 105 cars. The frequency distribution describing average miles per gallon (mpg) appears in the following table. Average mpg 15 ≤ x < 20 Frequency 8 20 ≤ x < 25 25 x 30 28 15 30 x 35 35 ≤ x < 40 40 ≤ x < 45 9 27 18 a-1. Construct the relative frequency distribution. Note: Round "Relative Frequency" to 4 decimal places. Average mpg Relative Frequency 15 ≤x≤20 20 ≤ x < 25 25 ≤ x < 30 30 ≤ x < 35 35 ≤ x <40 40 ≤ x < 45 a-2. What proportion of the cars got at least 40 mpg but less than 45 mpg? Note: Round your answer to 4 decimal places. Proportion of cars a-3. What proportion of the cars got less than 35 mpg? Note: Round your answer to 4 decimal places. Proportion of cars a-4. What proportion of the cars got 35 mpg or more? Note: Round your answer to 4 decimal places. Proportion of cars
