The scatterplot displays the number of pretzels students could grab with their dominant hand and

their handspan, measured in centimeters. An analysis

was completed and the computer output is shown

Using the computer output, the slope of the least-

squares regression line means for each additional

pretzel, the handspan will increase by about 1.585

cm.
