Question

suppose the exponential regression equation for some data is y=5.368 *2.273^x, what is predicted value of y? round your answer to the nearest whole number.

Answer 1

Given:

The exponential regression equation for some data is,

`y=5.368*2.273^x`

The value of x is,

`x=4`

Required:

Predicted value of y, rounded to the nearest whole number.

Answer:

The predicted value of y is,

`\begin{gathered} y=5.368*2.273^x \\ y=5.368*(2.273)^4 \\ y=5.368*26.6930 \\ y=143.29 \end{gathered}`

Hence, the value rounded to the nearest whole number is,

`y=143`

Final Answer:

The predicted value of y is,

`y=143`
