Mathematics (2019) Grade(s): 09-12 - Mathematical Modeling

MA19.MM.22

Conduct a randomized study on a topic of student interest (sample or experiment) and draw conclusions based upon the results.

COS Examples

Example: Record the heights of thirty randomly selected students at your high school. Construct a confidence interval to estimate the true average height of students at your high school. Question whether or not this data provides significant evidence that your school’s average height is higher than the known national average, and discuss error probabilities.
