mr. davis is a gym teacher. yesterday, he recorded how many laps each of his students ran around the gym during class. this box plot shows the results. laps around the gym what percent of students ran 10 or more laps? %
Answer
Explanation:
Step1: Identify quartiles from box - plot
The box - plot has the following features: The left - hand side of the box is the first quartile ($Q_1$), the line inside the box is the median ($Q_2$), and the right - hand side of the box is the third quartile ($Q_3$). Here, $Q_1 = 8$, $Q_2=9$, $Q_3 = 10$.
Step2: Calculate the percentage
The inter - quartile range (IQR) divides the data into four equal parts, each representing 25% of the data. The data to the right of $Q_3$ represents 25% of the data, and the data between $Q_2$ and $Q_3$ represents 25% of the data. Since we want the percentage of students who ran 10 or more laps (starting from $Q_3$), the percentage is 50%.
Answer:
50
