Based on the data shown below, calculate the regression line (each value to two decimal places) y = \boxed{} x + \boxed{} \begin{array}{|c|c|} \hline x & y \\ \hline 1 & 22.8 \\ 2 & 21.26 \\ 3 & 17.22 \\ 4 & 16.18 \\ 5 & 13.74 \\ 6 & 9.2 \\ \hline \end{array}

Step 1
x̄ = (1 + 2 + 3 + 4 + 5 + 6)/6 = 3.5 ȳ = (22.8 + 21.26 + 17.22 + 16.18 + 13.74 + 9.2)/6 = 16.75 Show more…
