Question
The Centers for Disease Control and Prevention (CDC) estimated the percent of individuals in each state who are classified as overweight or obese in different years. They calculated the estimates separately for three different age classes, including children (2–4 years old), adolescents (students in grades 9–12), and adults (aged 18 years and older).
The boxplots and fivenumber summaries apply to the data sets of two different age classes. Match the appropriate descriptions to the data sets.

Ans:
1)
The distribution skewed to left(As left whisker is longer)
25% of the values are less than 26.4
25% of the values are more than 31.08
2)Q1 is the point below which 25% of the values falls.
As,first quartile,Q1=11.25,which tells us that 25% of the values are less than 11.25
Distribution is close to symmetrical.
25% of the values are more than 13.5(as Q3=13.5,which tellus that 75% data falls below this and 25% above this)
