The accompanying data are the shoe sizes and heights (in inches) of
14
men. Find the equation of the regression line. Then construct a scatter plot of the data and draw the regression line. Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not.
| (a)
xequals=11.511.5 |
(b)
xequals=8.08.0 |
(c)
xequals=15.515.5 |
(d)
xequals=10.0 |
