D frequency divided by the total frequency. Roughly 25 percent of the gas stations in each state charge a price between $3.00 and $3.49; about 50 percent charge a price between $3.50 and $3.99; and about 25 percent charge a price between $4.00 and $4.49. c. 2% SPSS Tutorials: Frequency Tables - Kent State University b. The sum of the relative frequencies for all classes will always equal C. frequency divided by the class interval. Similarly, the relative frequency of prices between $3.75 and $3.99 equals 4/20 = 0.20 = 20 percent. The data is summarized in the following table: When a class interval is expressed as 100 up to 200, _________________________. Which of the following is the correct frequency distribution?
