Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary. (47, 8), (46, 10), (27, 10) y? = 4.88 + 0.625x y? = 11.538 - 0.055x y? = 4.98 + 0.725x y? = 4.98 + 0.425x

Step 1
The x-values are 47, 46, and 27, and the y-values are 8, 10, and 10. The mean of x, denoted as x̄, is (47+46+27)/3 = 40. The mean of y, denoted as ȳ, is (8+10+10)/3 = 9.33. Show more…
