Step 1
$\bar{x} = \frac{16 + 20 + 12 + 10 + 9 + 9}{6} = 12.67$ $\bar{y} = \frac{8 + 13 + 9 + 2 + 6 + 4}{6} = 7$ Show more…

3. Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary. x: 0, 3, 4, 5, 12 y: 8, 2, 6, 9, 12 y* = 4.98 + 0.725x y* = 4.98 + 0.425x y* = 4.88 + 0.625x y* = 4.88 + 0.525x
