cost answer to the nearest whole number. Perform a least$-$squares regression analysis on Garfield's data.

Note: Use Microsoft Excel or a statistical package to find the coefficients using least$-$squares regression. Round your answers

to $3$ decimal places. Determine how well this regression analysis explains the data.

Note: Round your regression statistics to three decimal places and, observation and percentage answer to the nearest whole

number.
