c. students who are at or below the 11^th percentile

d. students who are at or above the 11^th percentile (b) Students whose GPAs are at or above the 94^th percentile of all students at their high school are eligible (called eligible in the local context), even if they are not in the top 11% of all students in the state. What percentage of students from each high school are "eligible in the local context"? a. 6% of students

b. 94% of students

8. (a) For runners in a race, a low time means a faster run. The winners in a race have the shortest running times. Is it more desirable to have a finish time with a high or a low percentile when running a race?For runners in a race it is more desirable to have a ---Select--- low high percentile for a finish time. A ---Select--- low high percentile means a short time which is ---Select--- slower faster . (b) The 20^th percentile of run times in a particular race is 5.2 minutes. Write a sentence interpreting the 20^th percentile in the context of the situation. (Enter you answers as whole numbers.)The 20^th percentile means that----- % of runners finished the race in 5.2 minutes or less and ------ % of runners finished the race in 5.2 minutes or longer.
