Question

A data set whose original x values ranged from 41 through 78 was used to generate a regression equation of ŷ=5.3x – 21.9. Use the regression equation to predict the value of y when x=70.392.9Meaningless result402.1349.1

Answer 1

We have the equation, and we will replace the x-value to find the regression value, as follows,

`\begin{gathered} y=5.3x-21.9 \\ y=5.3(70)-21.9 \\ y=349.1 \end{gathered}`

The answer is d.349.1
