Lassiter Company used the method of least squares to develop a cost equation to predict the cost of moving materials. There were $80$ data points for the regression, and the following computer output was generated:

Intercept

Slope

Coefficient of correlation

Standard error

$$18,000$

$13$

$0\mathrm{.}94$

$$220$

The activity driver used was the number of moves.

Required:

What is the cost formula?

$Y=$$$,+$$$,x$

Using the cost formula, predict the cost of moving materials if $330$ moves are made.

$

What percentage of the variability in moving cost is explained by the number of moves? $($Round percentage to two decimal places.$)$

$\%$
