Answer:The equation of best fitted line is given as follows
The y intercept 3.787 represents the height of that is independent of Arm span.
The height of the person whose arm span is 66 inches is 66.817 inch.
The arm span of a person whose height is 74 inches is 73.52 inch
According to the given data the arm span and heights are given in inches
Using Microsoft excel we can draw the scatter plot of both the variables such that arm span is on X axis and Height is on Y axis
The image for the excel work done showing calculations and scatter plot is attached.
Now we can fit the linear tread line and to find out the equation of fitted line just tick on the " show equation" line option of trend line fitting
The equation of best fitted line is given as follows
Slope of line of best fit = 0.955
So we can conclude that height (Y) is related to Arm span according to equation (1)
Equation (1) shows the equation of line of best fit for the given data
The y intercept 3.787 represents the height of that is independent of Arm span.
So the height of the person whose arm span is 66 inches is given following
Similarly the arm span of a person whose height is 74 inches
