Multiple Choice

$\begin{array}{c|c|c|c|c|c}\overline{\mathrm{x}} & \mathrm{s}_{\mathrm{x}} & \overline{\mathrm{y}} & \mathrm{s}_{\mathrm{y}} & \mathrm{r} & \hat{\mathrm{y}}=\mathrm{b}_{0}+\mathrm{b}_{1 \mathrm{x}} \\\hline 10 & 5 & ? & ? & -0.8 & \hat{\mathrm{y}}=200-2 \mathrm{x}\end{array}$

• A) \(\overline{y}\) = 220; \(s _ { y }\) = 12.50
• B) \(\overline{y}\) = 190; \(s _ { y }\) = 0.32
• C) \(\overline{y}\) = 210; \(s _ { y }\) = 6
• D) \(\overline{y}\) = 180; \(s _ { y }\) = 12.50
• E) \(\overline{y}\) = 20; \(s _ { y }\) = 2.50
