So the number of people with 41-50 is 2; the number of people with 51-60 is 3; the number of people with 61-70 is 5; the number of people with 71-80 is 8; the number of people with 81-90 is 6; is 6. Arrange the scores of 30 people from low to high, the median is half of the sum of the 15th number and the 16th number; the 15th number and the 16th number must be in the score range of 71-80 points< /p>
