a$.$ Use these data to develop an estimated regression equation that could be used to predict the total cost for a given production volume. Do not round

intermediate calculations.

Compute $b_1$ and $b_0($to $1$ decimal$).$ Do not round intermediate calculations.

Complete the estimated regression equation $($to $1$ decimal$).$ Do not round intermediate calculations.

hat$(y)=$

$3+gra{d}_x$

b$.$ What is the variable cost per unit produced $($to $2$ decimal$)?$ Do not round intermediate calculations.

$

c$.$ Compute the coefficient of determination $($to $3$ decimals$).$ Do not round intermediate calculations. Note: report $r^2$ between $0$ and $1.$

$r^2=$

What percentage of the variation in total cost can be explained by the production volume $($to $1$ decimal$)?$ Do not round intermediate calculations.

$\%$

d$.$ The company's production schedule shows $500$ units must be produced next month. What is the estimated total cost for this operation $($to the nearest whole

number$)?$ Do not round intermediate calculations.
