Question

A data set whose original x values ranged from 38 through 65 was used to general a regression equation of ŷ = -4.4x + 2.6. Use the regression equation to predict the value of y when x=39.174.2-169.097.0Meaningless result

Answer 1

The predicted value of y when x=39 is -169.

Explanation:

To predict the value of y when x=39, we simply take the regression equation and plug in the given x-value, as following:

`\begin{gathered} y=-4.4(39)+2.6 \\ \\ \Rightarrow y=-169 \end{gathered}`

This way, we can conclude that the predicted value of y when x=39 is -169
