question 22

Multiple Choice

The following table lists values measured for 10 consecutive eruptions of the geyser Old Faithful in Yellowstone National Park. They are the duration, in minutes, of the eruption $\left( x _ { 1 } \right)$ , the dormant Period before the eruption $\left( x _ { 2 } \right)$ , and the dormant period after the eruption (y) .

$\begin{array} { l l l } x _ { 1 } & x _ { 2 } & y \\3.5 & 80 & 84 \\4.1 & 84 & 50 \\2.3 & 50 & 93 \\4.7 & 93 & 55 \\1.7 & 55 & 76 \\4.9 & 76 & 58 \\1.7 & 58 & 74 \\4.6 & 74 & 75 \\3.4 & 75 & 80 \\4.3 & 80 & 56\end{array}$

Construct the multiple regression equation $\hat { y}$ =b₀+b₁x₁+b₂x₂

• A) \(\hat { y }\)=122.22-1.85 x₁-0.62 x₂
• B) \(\hat { y }\)=118.78-1.7675 x₁-0.5856 x₂
• C) \(\hat { y }\)=-0.62-1.85 x₁+122.22 x₂
• D) \(\hat { y }\)=-0.5856-1.7675 x₁+118.78 x₂
