Question: Height and arm span: Your arm span is the distance between the middle fingertips on each hand when your arms are stretched out as far

Height and arm span: Your arm span is the distance between the middle fingertips on each hand when your arms are stretched out as far as you can reach. It is commonly thought that a person’s arm span is approximately equal to his or her height. Investigate this by measuring each student’s arm span and height and computing the least-squares regression line where x represents arm span and y represents height. Test the hypothesis H0: β1 = 1 versus H1: β1 ≠ 1.
