Estimate the sample regression equation that enables us to predict the price of a sedan on the basis of its age and mileage.

Note: Negative values should be indicated by a minus sign. Round your answers to $2$ decimal places. $[$If you are using R to obtain the output, then first enter the following command at the prompt: options$($scipen$=10).$ This will ensure that the output is not in scientific notation.$]$

Interpret the slope coefficient of Age.

multiple choice

The slope coefficient of Age is $606\mathrm{.}23,$ which suggests that for every additional year of age, the predicted price of car decreases by $$606\mathrm{.}23.$

The slope coefficient of Age is $0\mathrm{.}07,$ which suggests that for every additional year of age, the predicted price of car decreases by $$0\mathrm{.}07.$

The slope coefficient of Age is $606\mathrm{.}23,$ which suggests that for every additional year of age, the predicted price of car decreases by $$606\mathrm{.}23,$ holding number of miles constant.

The slope coefficient of Age is $0\mathrm{.}07,$ which suggests that for every additional year of age, the predicted price of car decreases by $$0\mathrm{.}07,$ holding number of miles constant.

Predict the price of a eight$-$year$-$old sedan with $68,000$ miles.

Note: Do not round intermediate calculations. Round final answer to $2$ decimal places.
