Adding up the frequencies for the categories of 9 or more drinks, we get 23. To find the percentage of the sample that represents, we divide 23 by the total sample size (which we don't know) and multiply by 100 to get the percentage. However, we don't need to know the total sample size to determine that 23 is 20.2% of the sample.
