Regents Exam: Algebra I August 2016 (Problem 33 of 37)

The video tutorial explains how to generate a linear regression equation using a graphing calculator and data on the median diameter of sand grains and beach slope. It guides viewers through creating a table, using the linear regression program, and predicting the slope of a beach with a given sand grain diameter. The final prediction is rounded to the nearest tenth of a degree.

Describe the process of generating a linear regression equation from the given data.

What is the median diameter of grains of sand used in the prediction?

What is the linear regression equation obtained from the data?

How do you predict the slope of the beach using the linear regression equation?

What is the final predicted slope of the beach when the median diameter is 0.65 millimeters?
