Slide 1
Trash Can Challenge
Let’s use mathematics to make our prediction so that we have a more statistically sound reason for who we predict will win.
Description of work area: Two tables appear, each displaying the number of students in a classroom and the average number of shots each student made.
The first table represents Ms. Watanabe’s class, which has eighteen students. The average shots the students made are: 10,10,2,6,5,8,1,4,10,3,8,10,3,8,10,3,4,1,10,2,1. Ms. Jibril’s class has 15 students. The average shots the students made are: 6,9,10,3,3,2,1,8,1,5,4,10,5,9,7.
(text on slide) Determine the relative frequency for each class. Type your answers in the blanks. Round your answers to the nearest hundredth.
HINT: To calculate the relative frequency for each class, add up the number of shots the students made and divide that number by the number of students in the class.
Description of work area: Two blanks appear. The first blank is to enter the relative frequency for Ms. Watanabe’s class. The second blank is to enter the relative frequency for Ms Jibril’s class.
Correct answers: Ms. Watanabe’s class: 5.44, Ms. Jibril’s class: 5.53
Slide 2
Whose class would you expect to win the trash can toss?
Description of work area: Two tables appear, each displaying the number of students in a classroom and the average number of shots each student made.
The first table represents Ms. Watanabe’s class, which has eighteen students. The average shots the students made are: 10,10,2,6,5,8,1,4,10,3,8,10,3,8,10,3,4,1,10,2,1. Ms. Jibril’s class has 15 students. The average shots the students made are: 6,9,10,3,3,2,1,8,1,5,4,10,5,9,7.
Two answer choices appear.
Correct Answer: B. Ms. Jibril’s Class. Ms. Jibril’s class should win because they have a higher relative frequency.
