BUSINESS DECISION: RELATIVE FREQUENCY DISTRIBUTION
In business, percents are frequently used to represent the portion of observations falling within classes of a frequency distribution. A relative frequency distribution expresses the distribution as percents. To convert a frequency distribution to a relative frequency distribution, divide each of the class frequencies (portion) by the total number of observations (base). Remember.
a. From the frequency distribution you constructed for the Internet Cafe in Exercise 3a. conver each class frequency to a relative class frequency, percents. Round your answers to tenths.
