Cumulative relative frequency graph problem

Nutritionists measured the sugar content (in grams) for 32 drinks at a popular coffee shop. A cumulative relative frequency graph for these data is shown below.
problem 1
An iced coffee has 15 grams of sugar.
Estimate the percentile of this drink to nearest whole percent.
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi
th percentile

problem 2
Estimate the median of the distribution of drinks.
Hint: Think about the 50th percentile.
