Question

Use a calculator or computer to find the least squares regression line, y = mx + b, where the independent variable x denotes the grip strength of the preferred hand and the dependent variable y denotes the grip strength of the nonpreferred hand. Enter the equation for the line below. (Use at least four decimal places in any constants in your answer.) y= What would the predicted grip strength in the nonpreferred hand be for a student with a preferred hand strength of 37 kg? strength = kg (round to nearest whole number) For each of the preferred grip strengths values, decided whether you

Explanation / Answer

we plug x=37

So

y= 0.834(37) +2.833

y= 30.858 + 2.833

y= 33.691

y=34 kg ( rounded)

that is for a preferred hand strength of 37 kg the non preferred hand strength is 34 kg
