Math Problem Statement
solve
Goran wants to find the average time it takes Washington High School students to run a lap around the track. So he will consider 55 students to find the average time.
(a) Which unit(s) could be used for the unit of measurement? Check all that apply.
(b) Which of the procedures below would be the best way to find the average time?
Solution
To solve the problem, we need to address both parts:
(a) Unit(s) for measurement:
Since we are measuring time, we should use "minutes" for the unit of measurement.
(b) Best procedure for finding average time:
The best procedure would be to "Randomly pick 55 students to run a lap around the track and measure their times." This ensures an unbiased selection and provides accurate timing data for calculating the average.
