A firm has modeled its experience with industrial accidents and found that the number of accidents

per year $($Y$)$ is related to the number of employees $($X$)$ by the regression equation Y $=3\mathrm{.}3+0\mathrm{.}049*$X$.$ RSquare is $0\mathrm{.}68.$ The regression is based on $20$ annual observations. The firm intends to employ $480$

workers next year. How many accidents do you project? How much confidence do you have in that

forecast?
