Suppose a newspaper surveys 250 adults in a neary town and inquires about their cell phone carrier. The accompanying table summa
rizes the results. Does this table describe a relative frequency distribution? Why or why not?
Choose the correct answer below.
A. No. The percents must be written as decimals in a relative frequency distribution.
B. No. Frequencies should be stated instead of percents.
C. No. The sum of the relative frequencies is 95%, not 100%
D . Yes. Categories are given , along with their corresponding percents .

Answer:
Option C
Step-by-step explanation:
Given that a newspaper surveys 250 adults in a nearby town and inquires about their cell phone carrier
When a frequency table is prepared we write number of items for each carrier A, B, C, D and E. In this case, the total frequency should add up to 250 and hence relative frequency if expressed in ratio as frequency/250 should add to 1.
Here because relative frequency the ratio is expressed as a percentage total should be equal to 100
But we find that this total amounts only to hence this cannot describe a relative frequency distribution.
Option C is right
