Question

Use the given data to find the best predicted value of the response variable.Ten pairs of data yield r = 0.003 and the regression equation Also, What is the best predicted value of y for x = 2? Use α = 0.057.08.05.017.0

Answer 1

Given:

r = 0.003

y- = 2 + 3x

y- = 5.0

Let's find the best predicted value of y for x = 2.

Use:

α = 0.05

Now, to solve, plug in 2 for x in the equation for y:

`\begin{gathered} y^-=2+3(2) \\ \\ y^-=2+6 \\ \\ y^-=8.0 \end{gathered}`

The best predicted value for y when x = 2, is 8.0

ANSWER:

8.0
