Explanation Given info: The data shows the frequency distribution for McDonald’s dinner service times (in seconds). Calculation: The total number of service times is, Sum of all frequencies = 7 + 22 + 14 + 2 + 5 = 50 Relative frequency: The formula is given by, Relative frequency for a class = frequency of a class sum of all frequencies Percentage for a class = frequency of a class sum of all frequencies × 100 % The relative frequency distribution is calculated as follows: Time (sec) Frequency Relative Frequency 60 – 119 7 7 50 × 100 % = 0.14 × 100 % = 14 % 120 – 179 22 22 50 × 100 % = 0
