Assessment Practice 19. June wants to know how many times most people have their hair cut each
year. She asks two of her friends from Redville and Greenburg, respectively,
to conduct a random survey. The results of the surveys are shown below.
Redville: 50 people surveyed
Greenburg: 60 people surveyed
Median number of haircuts: 7
Median number of haircuts: 65
Mean number of haircuts: 7.3
Mean number of haircuts: 76
June infers that most people get 7 haircuts per year. Based on the survey
results, is this a valid inference? Explain.
