The table below shows the heights of people in centimetres applying for the school of physical education. Using a frequency table, find the percentage of the ones whose heights are cm or less, approximated to the nearest hundredth if needed.
Make a frequency table of sets.
To find the percentage of students whose heights are less than 160 centimetres, divide the number of students in the set for by the total number of students, and multiply by 100.
It is enough to calculate the percent to three decimal places, because we need to round the result to the nearest hundredth.
Then round to the nearest hundredth.
