Odette plants basil from seed and each day measures the height of the plants compared to the soil line. She records her measurements in a scatter plot. Odette calculates the equation of the least squares regression line: Predicted Height = 0.32 • Days in Soil – 1.72 Use the drop-down menus to complete the statements below about what this linear model tells you about the height of a basil plant.

Answer:

The slope of the least squares regression line is:

0.32

The units of the slope of the line are:

centimeters per day.

The slope of the line tells you that for each new day you can predict that a plant's height will increase by about 0.32 centimeters.

The y-intercept of the least square regression line is:

-1.72

The units of the y-intercept of the line are:

centimeters.

The y intercept:

Typical height compared to the soil line.
