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

Step 1

Mean of x values: $\bar{x} = \frac{3+5+12+9+8+2+6+9+12}{9} = \frac{66}{9} = 7.333$ Mean of y values: Since we don't have the y values, we can't calculate the mean of y values directly. However, we can use the given regression line equations to find the correct Show more…
